Answer 6

which ones do u need help with

the integrals and the 2nd derivatives

Answer 8

\[\frac{d^2}{dx^2}(x^2sinx+2xcosx-2sinx)\]first derivative\[\frac{d}{dx}(x^2sinx+2xcosx-2sinx)\]\[=2xsinx+x^2cosx+2cosx-2xsinx-2cosx\]\[=2xsinx+x^2cosx-2sinx\]now for the second derivative find the derivative of the first derivative\[\frac{d}{dx}(2xsinx+x^2cosx-2sinx)\]
