integral of (cos(x))/(sqrt(3-sin^2(x)))

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

arcsin (\frac{1}{3} sin (x)) + C

Solution steps

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

Apply u-substitution

: \int \frac{1}{3 - u ^{2}} d u

= \int \frac{1}{3 - u ^{2}} d u

Apply Trigonometric Substitution

: \int 1 d v

= \int 1 d v

Integral of a constant:

\int a d x = a x

= 1 \cdot v

Substitute back

= 1 \cdot arcsin (\frac{1}{3} sin (x))

Simplify

= arcsin (\frac{1}{3} sin (x))

Add a constant to the solution

= arcsin (\frac{1}{3} sin (x)) + C

\int \frac{x + 9}{x ( x + 2 )} d x

\int (x + 9)^{2} d x

\int \frac{1}{( x ^{2} - 1 ) ( x - 1 )} d x

\int (u^{\frac{3}{2}} - 3 u + 14) d u

\int arctan (x) \frac{1}{x ^{2}} d x
