Given `y=(5x)/root(3)(1-x^2)+sin^2(2x+3)` we are asked to find `(dy)/(dx)` :
Rewrite as `y=5x(1-x^2)^(-1/3)+sin^2(2x+3)`
Use the product rule and the chain rule on the first term, and use the chain rule twice on the second term:
Factor out the common factor of `5(1-x^2)^(-4/3)` from the first two terms and use the double angle identity on the last term:
