Now I got it thank you Sir
but I know it might be annoying to ask more about it but here is my doubt in your worked solution

astarmathsandphysics:
I used the identity 1-cos^2 x + sin^2 x and rearranged it to give sin^2 x = 1-cos^2 x

why the integration of the 1 in( 1-cos^2x) not X following the rule (x^n+1)/(n+1)
astarmathsandphysics:
write 1 as x^0 then add one to the power and divide by the new power to give x^1/1=x
