Inverse functions calculator


Introduction to inverse function calculator
Every bijective functions has inverse. In this article let me help you on inverse functions calculator. The function f:R→R defined by f(x) =sinx is not one one, since f(0) = 0=f(π) and hence f is not a bijection. If we restricts the domain and codomain, the function f(x)= sinx may be converted into a bijection. The restricted bijective sine function is denoted by Sinx.
Definition: The function f:[-π/2, π/2] →[-1,1] defined by f(x)=sinx is a bijection. This could also help us on sigma symbol. The inverse of f froms [-1, 1] into [-π/2, π/2] is also a bijection. This functions are inverse function of Arc sine function. It is denoted by sin-1 or Arc sin.
