integral of ((cos(x))/(sqrt(sin(x)-1)))

\int (\frac{cos ( x )}{sin ( x ) - 1}) d x

2 sin (x) - 1 + C

Solution steps

\int \frac{cos ( x )}{sin ( x ) - 1} d x

Apply u-substitution

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

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

Apply u-substitution

: \int 2 d v

= \int 2 d v

Integral of a constant:

\int a d x = a x

= 2 v

Substitute back

= 2 sin (x) - 1

Add a constant to the solution

= 2 sin (x) - 1 + C

\int (1 + (4 x + 2)^{2}) d x

\int \frac{5 x ^{2} + 2 x e ^{x} - 1}{x} d x

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

\int tan^{4} (x) \cdot sec^{4} (x) d x

\int 18 θ sin (18 θ^{2}) d θ
