What is the derivative of #-1/(sin(x)^2)#? Calculus Differentiating Trigonometric Functions Derivative Rules for y=cos(x) and y=tan(x) 1 Answer Andrea S. Dec 26, 2016 #d/(dx) (-1/sin^2x) = (2cosx)/(sin^3x)# Explanation: Based on the chain rule: #d/(dx) (-1/sin^x) = d/(dsinx) (-1/sin^2x) * (dsinx)/(dx)= 2/(sin^3x)cosx# Answer link Related questions What is the derivative of #y=cos(x)# ?
