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

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

ln ∣ 3 + sin (t) ∣ + C

Solution steps

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

Apply u-substitution

= \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 (t)

= ln ∣ 3 + sin (t) ∣

Add a constant to the solution

= ln ∣ 3 + sin (t) ∣ + C
