DefinitionThe process of obtaining derivative of trigonometric function are always related to the inverse trig functions like sin inverse,cos inverse, tan inverse etc. They are tools we use in a lot of calculus problems, integration, differential equations. For Example, The derivative of inverse sine function is ddxsin−1(x)=1Hence,x2−2Solution, Likewise, the derivative of the inverse tangent function is dxdtan−1(x)=1+x21.
