如上图所示,图左对应函数 y=\sin x, x\in\left[ -\frac{\pi}{2},\frac{\pi}{2} \right] 的图象,图右为其反函数 y=\sin^{-1}x 或y=\arcsin x 的图象. 注意到: \sin^{-1}x=y\Leftrightarrow \sin y=x, -\frac{\pi}{2}\leq y \leq \frac{\pi}{2} . 反余弦函数 图记1.6-...
(I must confess that, in spite of working through the chapter on inverse circular functions, I could barely proceed with this problem. Note what it asks to prove : ##x\sqrt{1-x^2}+\ldots## and how much is that at odds with the formula (1 above) of adding two ##sin^{-1}##...

still some python interaction necessary to handle parts of the data model that are still in Python, mainly for handling parameter expressions. But otherwise the entirety of the pass operates in rust now. This is just a first pass at the migration here, it moves the pass to ...
Write $\cot^2(x)-\csc^2(x)$ In terms of sine and cosine and simplify So then $\dfrac{\cos ^2(x)}{\sin^2(x)} -\dfrac{1}{\sin^2(x)} =\dfrac{\cos^2(x)-1}{\sin^2(x)} =\dfrac{\sin^2(x)}{\sin^2(x)}=1$ Really this shrank to 1 Ok did these on cell so.....
c=sin−1(s1−s3s2+s1−s3) d=1n(π−c) In this context: s1 is the function output value at the beginning of the domain. s2 is the function output value at the end of the domain. s3 is the maximum output value of the function. n is the end of the function dom...
