integral of 2sin(x)+4

\int 2 sin (x) + 4 d x

- 2 cos (x) + 4 x + C

Solution steps

\int 2 sin (x) + 4 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 2 sin (x) d x + \int 4 d x

\int 2 sin (x) d x = - 2 cos (x)

\int 4 d x = 4 x

= - 2 cos (x) + 4 x

Add a constant to the solution

= - 2 cos (x) + 4 x + C

\int \frac{π}{4 W} cos (\frac{π x}{2 W}) d x

\int (2 x - 1) sin (2 x) d x

\int \frac{5 x}{5 x ^{2} - 7} d x

\int 3 x^{2} - 4 x^{3} d x

\int x^{2} sin (- 6 x) d x
