    Problem is: \[\int\limits_{-\frac{ \pi }{ 2 }}^{\frac{ \pi }{ 2 }}(\sin^3x \cos x+\sin x \cos x)dx\]

    \[\sin ^{2} x is meant (\sin(x))^{2}\] so you are using quotient rule for sin square. and cos x anti-derivative was sin x

    Then take the number when you plug pi/2 subtract the number when you plug -pi/2 and get the answer
