integral of sin(x)+cos^2(x)

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

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

Solution steps

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

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int sin (x) d x + \int cos^{2} (x) d x

\int sin (x) d x = - cos (x)

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

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

Add a constant to the solution

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

\int x ln (7 x) d x

\int \frac{1}{( 2 - 5 x ) ^{3}} d x

\int ln (t) d t

\int \frac{4 x}{x - 2} d x
