integral of cos(7x+4)

\int cos (7 x + 4) d x

\frac{1}{7} sin (7 x + 4) + C

Solution steps

\int cos (7 x + 4) d x

Apply u-substitution

: \int cos (u) \frac{1}{7} d u

= \int cos (u) \frac{1}{7} d u

Take the constant out:

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

= \frac{1}{7} \cdot \int cos (u) d u

Use the common integral:

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

= \frac{1}{7} sin (u)

Substitute back

u = 7 x + 4

= \frac{1}{7} sin (7 x + 4)

Add a constant to the solution

= \frac{1}{7} sin (7 x + 4) + C

\frac{8}{s ^{2} + 9} \cdot e^{- 5 s}

(sec (x))^{2}

\int 3 sin (\frac{x}{2}) - 2 cos (\frac{2 x}{5}) d x

\frac{d}{d x} (2 x y^{2} + 4)

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