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

1 + cos (x)

\frac{( 2 x + 3 )}{( 3 x + 4 )}

\frac{( 1 + x ^{2} ) ^{\frac{1}{2}}}{x}

2 x cos (x^{2})

\frac{sin ^{2} ( x )}{( 1 + sin ^{2} ( x ) )}
