integral of 5picos(pi)x

\int 5 π cos (π) x d x

- \frac{5 π x ^{2}}{2} + C

Solution steps

\int 5 π cos (π) x d x

Take the constant out:

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

= 5 π cos (π) \cdot \int x d x

5 π cos (π) = - 5 π

= (- 5 π) \cdot \int x d x

Apply the Power Rule

= (- 5 π) \frac{x ^{2}}{2}

Simplify

(- 5 π) \frac{x ^{2}}{2} : - \frac{5 π x ^{2}}{2}

= - \frac{5 π x ^{2}}{2}

Add a constant to the solution

= - \frac{5 π x ^{2}}{2} + C
