Triangular Maple
The clumps of triangular maple had many uses: - ** Landscape **: - ** Courtyard shade tree **: Its branches and leaves are dense, and it can form a dense shade effect in summer. It is suitable for solitary or clustered shade trees to provide shade for the courtyard. For example, when building a cool summer courtyard, you can plant several clumps of triangular maple trees in the front yard with other trees. - ** Street trees and revetment trees **: It can be used as street trees and revetment trees. It is also suitable for planting on lakeshore, stream, valley, and lawn. It can play a role in beautification and protection. - ** Landscape **: Can be used to decorate pavilions, corridors, and rocks to add natural beauty. Old piles were often made into bonsais. The trunk was twisted and raised, which was quite strange. - ** Hedge **: In the Jiangnan area, there is a situation where the triangular maple is planted as a hedgerow. After a year, the branches will be connected and connected, giving it a unique flavor. - ** Greening project **: Because of its beautiful tree shape and beautiful leaf shape, the leaves will turn dark red or red in winter, and the clustered canopy that spreads to the surroundings makes its ornamental value maximize, so it can be widely used in the community park and urban green projects. For example, the 2 - 10 meters tall, full crown of clumps of triangular maple can be used for community park green. "Life Like a White Birch" is equally exciting.

Triangular Maple
Buerger maple was a decidual tree, up to 20 meters tall, with brown or dark brown bark. Its leaves are papery, oval or obovate, 6 - 10 cm long, 3-lobed or undivided, apex short acuminate, base round, entire or upper part sparsely serrate, young leaves below and petiole densely pilose, white powder below, base veins 3. Flowers mostly in a terminal corymb, blooming after the leaves have grown up; Sepals 5, yellowish green, ovate, petals 5, pale yellow. Samara yellowish-brown; nutlets are particularly raised, wings and nutlets are 2 - 2.5 cm long, open into an acute angle or nearly erect, flowering in April, fruiting in August. Buerger maple was distributed in Shandong, Henan, Jiangsu, Zhejiang, Anhui, Jiangxi, Hubei, Hunan, Guizhou, and Guangdong provinces in China. It was born in broad-leaved forests at an altitude of 300 - 1000 meters. It had strong adaptability and liked warm and humid climates. It was suitable for growing in fertile, loose and well-drained sandy loam. Buerger maple had a strong resistance and could be used as a pioneer tree species in wasteland plantation with significant ecological benefits. The wood was hard and dense, and could be used to make tools. The seeds could also be used to extract oil, which had a certain economic value. Its leaves were dense and its autumn leaves were red. It was often used as a roadside tree or as a potted plant. It was very ornamental. In terms of leaf characteristics, it is usually 3-lobed, triangular lobes, dark green leaves with white powder on the back; samara is brownish-yellow, two wings are sickle-shaped, fruit period is September to October.

The Universal Formula of Triangular Function and Inverse Triangular Function
三角函数的万能公式，可以把所有三角函数都化成只有\(tan(\frac{\alpha}{2})\)的多项式，实现将角统一为\(\frac{\alpha}{2}\)、函数名称统一为\(tan\)等作用，具体公式如下： 1. \(\sin\alpha = \frac{2\tan(\frac{\alpha}{2})}{1 + \tan^{2}(\frac{\alpha}{2})}\) 2. \(\cos\alpha=\frac{1 - \tan^{2}(\frac{\alpha}{2})}{1 + \tan^{2}(\frac{\alpha}{2})}\) 3. \(\tan\alpha=\frac{2\tan(\frac{\alpha}{2})}{1 - \tan^{2}(\frac{\alpha}{2})}\) 反三角函数常见公式如下： **一、反正弦三角函数计算公式** 1. 当\(xy\leq0\)或\(x^{2}+y^{2}\leq1\)时，\(\arcsin x+\arcsin y = \arcsin(x\sqrt{1 - y^{2}}+y\sqrt{1 - x^{2}})\); 2. 当\(x > 0\)且\(y > 0\)且\(x^{2}+y^{2}>1\)时，\(\arcsin x+\arcsin y=\pi - \arcsin(x\sqrt{1 - y^{2}}+y\sqrt{1 - x^{2}})\); 3. 当\(x < 0\)且\(y < 0\)且\(x^{2}+y^{2}>1\)时，\(\arcsin x+\arcsin y = -\pi - \arcsin(x\sqrt{1 - y^{2}}+y\sqrt{1 - x^{2}})\); 4. 当\(xy\leq0\)或\(x^{2}+y^{2}\leq1\)时，\(\arcsin x - \arcsin y=\arcsin(x\sqrt{1 - y^{2}}-y\sqrt{1 - x^{2}})\); 5. 当\(x > 0\)且\(y < 0\)且\(x^{2}+y^{2}>1\)时，\(\arcsin x - \arcsin y=\pi - \arcsin(x\sqrt{1 - y^{2}}-y\sqrt{1 - x^{2}})\); 6. 当\(x < 0\)且\(y > 0\)且\(x^{2}+y^{2}>1\)时，\(\arcsin x - \arcsin y = -\pi - \arcsin(x\sqrt{1 - y^{2}}+y\sqrt{1 - x^{2}})\)。 **二、反余弦三角函数计算公式** 1. 当\(x + y\geq0\)时，\(\arccos x+\arccos y = \arccos(xy - \sqrt{1 - x^{2}}\sqrt{1 - y^{2}})\); 2. 当\(x + y < 0\)时，\(\arccos x+\arccos y = 2\pi - \arccos(xy - \sqrt{1 - x^{2}}\sqrt{1 - y^{2}})\); 3. 当\(x\geq y\)时，\(\arccos x - \arccos y = -\arccos(xy + \sqrt{1 - x^{2}}\sqrt{1 - y^{2}})\); 4. 当\(x < y\)时，\(\arccos x - \arccos y=\arccos(xy + \sqrt{1 - x^{2}}\sqrt{1 - y^{2}})\)。 **三、反正切三角函数计算公式** 1. 当\(xy < 1\)时，\(\arctan x+\arctan y=\arctan\frac{x + y}{1 - xy}\); 2. 当\(x > 0\)，\(xy > 1\)时，\(\arctan x+\arctan y=\pi+\arctan\frac{x + y}{1 - xy}\); 3. 当\(x < 0\)，\(xy > 1\)时，\(\arctan x+\arctan y = -\pi+\arctan\frac{x + y}{1 - xy}\); 4. 当\(xy > - 1\)时，\(\arctan x - \arctan y=\arctan\frac{x - y}{1 - xy}\)。 <a href="/?from=ask_words" style="color:red" target="_blank">点击前往免费阅读更多精彩小说</a>
Photograph and Walk
There was a close connection between photography and walking. Walking provided a rich source material and a variety of shooting scenes for photography. For example, when walking in Hangzhou Iron and Steel Park, one could use the light and shadow composition of the escalator in the three-story sinking space, or use the turning staircase lines as the background, highlight the main body through color contrast, and increase the layering with the help of oblique light to carry out photography creation; Walking on the ancient Shu Road in Guangyuan, even the misty weather could become a unique photography picture; Walking along the railway, one could carry out photography creation of the train track. Different areas during the journey, such as Yunxi Botanic Garden in Guangzhou, could be used as photography locations. In short, walking allowed the photographer to come into contact with more different elements such as light, scenery, space, etc., thus enriching the content and expressiveness of the photography work, while photography could record what they saw and felt while walking. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The Metaphor of Photograph
There were many kinds of metaphor for photography. For example, the relationship between photography and photography could be compared to the relationship between mathematics and calculation; photography could be compared to makeup; and people who recorded good times with a camera could be compared to time architects. In terms of the use of light, people described the camera as a " brush " and compared light to " paint." In terms of color, there were warm and cool colors. For example, red represented warm colors, and ice represented cold colors. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Photograph animation
The following are some operations related to photo animation: - ** Creating photo-taking animations with specific apps (such as Pixaloop)** - To import photos: click on the "album" icon in the upper left corner to import the photos that need to be "moved." The interface will have animation, sky, coverage, elements, camera effects, adjustment, and other functions. - [Animation Function: Mainly uses the "animation" function. After opening it, there are functions such as path, anchor, speed, and so on.] The "path" determines the direction of the "movement" of the picture. For example, if you want the clouds in the photo to move to the right, you can draw a few strokes to the right, but the whole picture will move at this time. To make the relatively static elements (such as mountains and characters) not be affected, you can use "anchor" to stop the animation, which is to add anchor points where you need to stop. You can also use the "Lock" function (suitable for people with trypophobia) to wipe out places that don't need animation. If you accidentally wipe too much, you can click the "Unlock" function to cancel it. You can also adjust the animation speed through "Speed". - ** Other functions to make photos move ** - Sky function: Similar to MIX's "One Touch Change Sky" function, it can change the sky while moving the sky. To make the effect more natural, you can click on the filter you choose to adjust the skyline, environment, details, and other options according to the image. - Overlay function: For "still" photos, click "Overlay" to see dynamic elements such as hearts, bubbles, and stars covering the entire picture. After selecting the appropriate special effects, use an eraser to wipe away the places that do not need to be covered by the special effects. - Element function: Different from Overlay, Element can add small animations to parts of the photo, such as butterflies, birds, smoke, fireworks, etc. You can use this function to add elements to double exposure photos to increase creativity. - [Special effects: Add movie effects by default, such as the push-pull and rocking techniques in movie shooting. You can add them with one click.] The generated GIFs were saved in a video format. The size could be selected, and the picture quality was 1080P. Some of the functions required the Pro to pay, but the basic functions were free and easy to operate. In addition, stop-motion animation is also related to photo animation. For example, you can use the iMotion App to shoot stop-motion animation. After installing and opening it, the main page has a total of five items. You can watch videos uploaded by users all over the world in the iMotion gallery. My movies has the shooting content and displays the movie usage and remaining memory capacity.(click the + sign to delete the current animation), there is a description of the button function in the help.(Although it's in English, it's not hard to understand). When creating a movie, click on new movies to enter the option settings. For stop motion animation, you usually choose to manually change the shooting mode. The shooting steps are to choose the front and rear cameras, name them, select the shooting mode, and then press Start to shoot. Enter the shooting interface and click Tools to set the picture mark, flash, grid lines, manual/auto focus, exposure compensation, white balance lock, etc. After shooting, you can adjust the frame speed. Finally, he chose the save format and clicked on the photo library to complete. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What makes a photograph a famous photograph that tells a story?
First, it should have a strong visual impact. For example, 'The Terror of War' by Nick Ut. The photo of the children running from a napalm attack is so powerful that it immediately grabs the viewer's attention and tells the horror story of war. Second, it often represents a significant moment in history like 'The Fall of the Berlin Wall'. The pictures of people climbing on the wall and celebrating symbolize the end of the Cold War. Third, it can also capture the essence of a social issue. 'AIDS in Africa' photos show the suffering of patients and the impact on society, thus telling a complex and important story.
