How do you differentiate #sin^2(x) * cos^2(x)#? Calculus Differentiating Trigonometric Functions Differentiating sin(x) from First Principles 1 Answer ali ergin May 21, 2016 #(d y)/(d x)=2 sin x cos^3 x-2 cos x*sin^3 x# Explanation: #y=sin^2 x*cos^2 x# #(d y)/(d x)=(sin^2 x)^'*cos^2 x+(cos^2 x)^'*sin^2 x# #(sin^2 x)^'=2sin x cos x# #(cos^2 x)^'=-2sin x cos x# #(d y)/(d x)=2 sin x cos x* cos^2 x-2 sin x cos x*sin^2 x# #(d y)/(d x)=2 sin x cos^3 x-2 cos x*sin^3 x# Answer link Related questions How do you differentiate #f(x)=sin(x)# from first principles?
