integral of cos(x)sqrt(sin(x)+1)

\int cos (x) sin (x) + 1 d x

sin (x) sin (x) + 1 - \frac{1}{3} (sin (x) + 1)^{\frac{3}{2}} + sin (x) + 1 + C

Solution steps

\int cos (x) sin (x) + 1 d x

Apply Integration By Parts

: sin (x) sin (x) + 1 - \int \frac{cos ( x ) sin ( x )}{2 sin ( x ) + 1} d x

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

\int \frac{cos ( x ) sin ( x )}{2 sin ( x ) + 1} d x = \frac{1}{3} (sin (x) + 1)^{\frac{3}{2}} - sin (x) + 1

= sin (x) sin (x) + 1 - (\frac{1}{3} (sin (x) + 1)^{\frac{3}{2}} - sin (x) + 1)

Simplify

= sin (x) sin (x) + 1 - \frac{1}{3} (sin (x) + 1)^{\frac{3}{2}} + sin (x) + 1

Add a constant to the solution

= sin (x) sin (x) + 1 - \frac{1}{3} (sin (x) + 1)^{\frac{3}{2}} + sin (x) + 1 + C

\int \frac{e ^{\frac{1}{x ^{2}}} + 2 x + ln ( x )}{x ^{3}} d x

\int \frac{1}{cos ( x ) + 2} d x

\int \frac{3}{( 1 - 2 x ) ^{2}} d x

\int (\frac{1}{4} x^{3} + 3 x^{2} - \frac{3}{4} x + 4) d x

\int e^{8 x} sin (e^{8 x}) d x
