integral of 4e^{2x}cos(yz)+3y^2

\int 4 e^{2 x} cos (yz) + 3 y^{2} d x

3 y^{2} x + 2 e^{2 x} cos (yz) + C

Solution steps

\int 4 e^{2 x} cos (yz) + 3 y^{2} 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 3 y^{2} d x + \int 4 cos (yz) e^{2 x} d x

\int 3 y^{2} d x = 3 y^{2} x

\int 4 cos (yz) e^{2 x} d x = 2 e^{2 x} cos (yz)

= 3 y^{2} x + 2 e^{2 x} cos (yz)

Add a constant to the solution

= 3 y^{2} x + 2 e^{2 x} cos (yz) + C

\int e^{x} cos (2) e^{x} d x

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

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

\int \frac{x + 5}{x + 4} d x

\int (x^{2} + 8) (x - 8) d x
