i have two questions, for both i need to find F'(x) of the function.
i think both are using the product rule but not 100% certain. All help much appreciated.
1 f(x)= ln(x^3-1/3x^2)
2 f(x)=e^cosx *sin(ln x)
Chain rule should be used for sureand
I will solve one of the question
as an example.(you may do other one by urself,ask if you have any doubt in solving)
differentiating we get
we may solve [d/dx(e^cosx)] saperately as it is a power function
