Explanation:
We want to find the derivative of
#y=ln(x^3sin(x^2))#
Using the properties of logarithms
#y=ln(x^3)+ln(sin(x^2))#
#color(white)(y)=3ln(x)+ln(sin(x^2))#
By the chain rule
#dy/dx=3/x+(d/dx(sin(x^2)))1/(sin(x^2))#
#color(white)(dy/dx)=3/x+2xcos(x^2)1/(sin(x^2))#
#color(white)(dy/dx)=3/x+2xcot(x^2)#
