A level math questions
Hello! I am stuck with this calc question.
A curve y=x^2cosx for 0<=x<=1/2pi is shown with maximum point M. Show by differentiation that the x coordinate of M satisfies the equation. tanx=2/x. I have found the derivative of dy/dx=cosx2x+(-sinxx^2) but this seems complicated to work with and I'm not sure the next steps to take to solve the question.
Thank you for help

Let dy/dx=0 and solve from there.
Also as a start, factor x out of the equation.
