integral of sin(-2x+1)

integral

sin (- 2 x + 1)

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

Solution steps

\int sin (- 2 x + 1) d x

Apply u-substitution

= \int - \frac{1}{2} sin (u) d u

Take the constant out:

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

= - \frac{1}{2} \cdot \int sin (u) d u

Use the common integral:

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

= - \frac{1}{2} (- cos (u))

Substitute back

u = - 2 x + 1

= - \frac{1}{2} (- cos (- 2 x + 1))

Simplify

= \frac{1}{2} cos (- 2 x + 1)

Add a constant to the solution

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