The relationship between the inverse function and the original function
If a function had an inverse function, then the original function and the inverse function were in a one-to-one correspondence, that is, an original function corresponded to an inverse function, and vice versa. From the perspective of domain and range, the domain and range of the inverse function were the domain and range of the original function. Moreover, if a function had an original function, there would be an infinite number of original functions. However, for a particular original function, it would only have one corresponding inverse function (under the condition that the inverse function existed). Read more exciting novels for free
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>
Derivation of the Inverse Tangent Function's Integration Transformation
反正切函数的积分可以通过分部积分法来推导。 设\(y = \arctan x\)，\(dy=\frac{1}{1 + x^{2}}dx\)。 根据分部积分公式\(\int u dv=uv-\int v du\)，对于\(\int\arctan xdx\)，令\(u = \arctan x\)，\(dv=dx\)，则\(du=\frac{1}{1 + x^{2}}dx\)，\(v=x\)。 所以\(\int\arctan xdx=x\arctan x-\int\frac{x}{1 + x^{2}}dx\)。 对于\(\int\frac{x}{1 + x^{2}}dx\)，令\(t = 1 + x^{2}\)，\(dt = 2xdx\)，则\(\int\frac{x}{1 + x^{2}}dx=\frac{1}{2}\int\frac{dt}{t}=\frac{1}{2}\ln|t|+C=\frac{1}{2}\ln(1 + x^{2})+C\)。 综上，\(\int\arctan xdx=x\arctan x-\frac{1}{2}\ln(1 + x^{2})+C\)。 <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>

What was the original function of the embryonic Chinese characters?
The embryonic Chinese characters were originally used to record sounds and tones. For example, ancient rhyme books and rhymes recorded syllables and tones in the form of Chinese characters. As time passed, the prototype of Chinese characters gradually developed more functions, such as expressing phoneme, syllable, tone, meaning, and so on. In the process of the evolution of Chinese characters, many embryonic Chinese characters evolved into formal Chinese characters, which became the foundation of modern Chinese characters. For example, the initial form of "Xu" was "Yan", which meant speaking, and later evolved into "Yu", which meant language or speech; the initial form of "Song" was "Shi", which meant poetry or praise, and later evolved into "Song", which meant praise or praise.

How does 'the thing' function in the original short story?
The 'thing' in the original short story functions in a way that is integral to the story's structure and meaning. It could act as a mystery that the characters and the readers are trying to figure out. This mystery creates suspense and keeps the readers engaged. It might also function as a connection between different parts of the story. For example, if 'the thing' is a key, it might unlock different events or revelations in the story. It could also function as a contrast to the normal world of the characters. If 'the thing' is something very strange or out of the ordinary, it highlights the normalcy of the characters' lives before its appearance and the upheaval it causes afterwards.
