y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴 y = arcsin x, x∈[–1,1], y∈[–π/2,π/2] sin x = 0 ←→ arcsin x = 0 sin x = 1/2 ←→ arcsin x = π/6 sin x = √2/2 ←→ arcsin x = π/4 sin x = 1 ←→ arcsin...
然而它实际上只是sin的部分反函数（partial inverse）。因为sin不是双射函数（bijective），它的x和y不...
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: ...

The value of arcsin 1 is equal to 90 degrees or π/2 radians. We can find the value of sin inverse 1 using the unit circle and its coordinates which are given by (cos x, sin x).
1. sininv cosinv taninv应该即系sin cos同tan既inverse function 即系例如当sin x = y既时候 sininv y = x. 而sinh cosh tanh叫做hyperbolic function. 在hyperbolic geometry入面 如果我地定义到一只直角三角形 咁呢个直角三角形既sin cos同tan既standard definition就系sinh cosh tanh. 2. ...
