Question

Help Please. Find the Derivative of y=2xcosx-2sinx and apply chain rule. Can you show the process of how to solve it?

Answer 1

if it is
\[f(x)=2x\cos(x)-2\sin(x)\] then the chain rule does not apply
only need the product rule

Answer 2

so there is no chain rule at all?

Answer 3

no because you have a product \(2x\sin(x)\) not a composite function

Answer 4

Can you show me how to solve?
