integral of sin(4x+pi)

\int sin (4 x + π) d x

\frac{1}{4} cos (4 x) + C

Solution steps

\int sin (4 x + π) d x

Rewrite using trig identities

= \int - sin (4 x) d x

Take the constant out:

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

= - \int sin (4 x) d x

Apply u-substitution

: \int sin (u) \frac{1}{4} d u

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

Take the constant out:

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

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

Use the common integral:

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

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

Substitute back

u = 4 x

= - \frac{1}{4} (- cos (4 x))

Simplify

= \frac{1}{4} cos (4 x)

Add a constant to the solution

= \frac{1}{4} cos (4 x) + C

(sin (\frac{3}{x}))^{^{'}}

\frac{d}{d x} (\frac{2 x ^{2}}{3})

(1 + x)^{- \frac{3}{5}}
