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 sin (u) \frac{1}{2} d u

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

x + 16

\frac{1}{( 35 - x )}

\frac{1}{( x ^{2} - 4 x )}

(2 x + 3)^{4}

e \cdot x^{2}
