Inverse Sine The inverse of the sine function is thearcsin function. Thus, if you know the ratio of sine of an angle, you can use arcsin to find the measurement of the angle. Arcsin can also be expressed as sin-1(x). Cosecant ...
arcsin 虽然也可以写成sin−1，然而它实际上只是sin的部分反函数（partial inverse）。因为sin不是双射...
Derivative $f’$ of the function $f(x)=\sin x$ is: \(\forall x \in ]-\infty, +\infty[ , f'(x) = \cos x\) Proof/Demonstration \[\begin{aligned} \frac{\sin (x+h)-\sin x}{h}&= \frac{\sin (x) \cos (h)+\cos (x) \sin (h)-\sin x}{h} \\ \frac{\sin (x...
拉氏反变换 (Inverse Laplace Ttansforms) 拉氏反变换是拉氏变换的相反运算,也就是若 f(t)的拉氏变换是 F(s) (即 L[f(t)]=F(s)),则 F(s) 的拉氏反变换即为 f(t),记成: L^{-1}[F(s)]=f(t) 。到目前为止,囚拉氏反变换的方法有: ...
