integral of x^3+sin(x)

\int x^{3} + sin (x) d x

\frac{x ^{4}}{4} - cos (x) + C

Solution steps

\int x^{3} + sin (x) d x

Apply the Sum Rule:

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

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

\int x^{3} d x = \frac{x ^{4}}{4}

\int sin (x) d x = - cos (x)

= \frac{x ^{4}}{4} - cos (x)

Add a constant to the solution

= \frac{x ^{4}}{4} - cos (x) + C
