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

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

arcsin (\frac{1}{2} sin (x)) + C

Solution steps

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

Apply u-substitution

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

= \int \frac{1}{2 - 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}{2} sin (x))

Simplify

= arcsin (\frac{1}{2} sin (x))

Add a constant to the solution

= arcsin (\frac{1}{2} sin (x)) + C

\int \frac{2 x ^{\frac{3}{2}}}{3 x} d x

\int 2 t + 7 d t

\int \frac{4 x}{4 x ^{2} + 1} d x

\int - e^{y} y^{2} d y

x + 2
