6.8.1 Inverse Trig Functions I(反三角函数I) 本课程将讨论超越函数的导数和积分, 包括双曲函数; 与应用集成的各种技术--由零件集成、部分分数、三角替代; 圆锥; 极性坐标; 无限序列和级数以及各种收敛性测试。
In calculus, sin−1x, tan−1x, and cos−1x are the most important inverse trigonometric functions. Nevertheless, here are the ranges that make the rest single-valued. If x is positive, then the value of the inverse function is always a first quadrant angle, or 0. If x is ...

We have 6 inverse trigonometric functions that are the inverses of the 6 basic trigonometric functions. The inverse trig derivatives are defined only in the domain of the inverse trigonometric functions which are stated as follows:Inverse Trigonometric FunctionDomain arcsin x [-1, 1] arccos x [-...
In this lesson, learn what inverse trigonometric functions are, including inverse sine and inverse cosine functions. See examples to learn how to...
Summary: The inverse trig functions (also called arcfunctions) are similar to any other inverse functions: they go from the function value back to the angle (or number). Their ranges are restricted, by definition, because an inverse function must not give multiple answers. Once you understand ...
