Derivatives of trigonometric functions

Here is the derivative of y = sin-1x and the corresponding integral. Inverse Cotangent. y = cot-1x = arccot x is the inverse function to x = tan y with the restriction 0 < y < (. In other words . y = cot-1 x is that angle y such that 0 < y < ( and cot y = x. Inverse Secant. ................
