integral of 4sin(5x+7)

\int 4 sin (5 x + 7) d x

- \frac{4}{5} cos (5 x + 7) + C

Solution steps

\int 4 sin (5 x + 7) d x

Take the constant out:

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

= 4 \cdot \int sin (5 x + 7) d x

Apply u-substitution

= 4 \cdot \int sin (u) \frac{1}{5} d u

Take the constant out:

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

= 4 \cdot \frac{1}{5} \cdot \int sin (u) d u

Use the common integral:

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

= 4 \cdot \frac{1}{5} (- cos (u))

Substitute back

u = 5 x + 7

= 4 \cdot \frac{1}{5} (- cos (5 x + 7))

Simplify

4 \cdot \frac{1}{5} (- cos (5 x + 7)) : - \frac{4}{5} cos (5 x + 7)

= - \frac{4}{5} cos (5 x + 7)

Add a constant to the solution

= - \frac{4}{5} cos (5 x + 7) + C
