integral of (cos(t))/(2+sin(t))

\int \frac{cos ( t )}{2 + sin ( t )} d t

ln ∣ 2 + sin (t) ∣ + C

Solution steps

\int \frac{cos ( t )}{2 + sin ( t )} d t

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 = 2 + sin (t)

= ln ∣ 2 + sin (t) ∣

Add a constant to the solution

= ln ∣ 2 + sin (t) ∣ + C

\int (x \cdot ln (x)) d x

\frac{d}{d j} (3 i + 4 j)

f (x) = sec^{2} (x) - 3

\int \frac{4 x ^{2} - 81}{x ^{3}} d x

\frac{d}{d x} (\frac{3}{8 ( x + 1 ) ^{\frac{5}{2}}})
