integral of (cos(x))/(3+sin(x))

\int \frac{cos ( x )}{3 + sin ( x )} d x

ln ∣ 3 + sin (x) ∣ + C

Solution steps

\int \frac{cos ( x )}{3 + sin ( x )} d x

Apply u-substitution

: \int \frac{1}{u} d u

= \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= ln ∣ u ∣

Substitute back

u = 3 + sin (x)

= ln ∣ 3 + sin (x) ∣

Add a constant to the solution

= ln ∣ 3 + sin (x) ∣ + C

\frac{\partial}{\partial y} (4 (x - y) e^{4 y + 5 x^{2}})

x \to a lim ((f (x))^{g (x)})

\int sin (8 x) cos (2 x) d x

x^{^{''}} + 5 x = 0

x^{2} sin (x) tan (x)
