integral of cos(5x-2)

\int cos (5 x - 2) d x

\frac{1}{5} sin (5 x - 2) + C

Solution steps

\int cos (5 x - 2) d x

Apply u-substitution

= \int cos (u) \frac{1}{5} d u

Take the constant out:

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

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

Use the common integral:

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

= \frac{1}{5} sin (u)

Substitute back

u = 5 x - 2

= \frac{1}{5} sin (5 x - 2)

Add a constant to the solution

= \frac{1}{5} sin (5 x - 2) + C
