integral of cos(t)+sin^3(t)

\int cos (t) + sin^{3} (t) d t

sin (t) - cos (t) + \frac{cos ^{3} ( t )}{3} + C

Solution steps

\int cos (t) + sin^{3} (t) d t

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int cos (t) d t + \int sin^{3} (t) d t

\int cos (t) d t = sin (t)

\int sin^{3} (t) d t = - cos (t) + \frac{cos ^{3} ( t )}{3}

= sin (t) - cos (t) + \frac{cos ^{3} ( t )}{3}

Add a constant to the solution

= sin (t) - cos (t) + \frac{cos ^{3} ( t )}{3} + C
