integral of 15xcos(1/2)x

\int 15 x cos (\frac{1}{2}) x d x

5 cos (\frac{1}{2}) x^{3} + C

Solution steps

\int 15 x cos (\frac{1}{2}) x d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 15 cos (\frac{1}{2}) \cdot \int xx d x

Simplify

xx : x^{2}

= 15 cos (\frac{1}{2}) \cdot \int x^{2} d x

Apply the Power Rule

= 15 cos (\frac{1}{2}) \frac{x ^{3}}{3}

Simplify

15 cos (\frac{1}{2}) \frac{x ^{3}}{3} : 5 cos (\frac{1}{2}) x^{3}

= 5 cos (\frac{1}{2}) x^{3}

Add a constant to the solution

= 5 cos (\frac{1}{2}) x^{3} + C
