integral of (9cos(x))

\int (9 cos (x)) d x

9 sin (x) + C

Solution steps

\int 9 cos (x) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 9 \cdot \int cos (x) d x

Use the common integral:

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

= 9 sin (x)

Add a constant to the solution

= 9 sin (x) + C

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

\int e^{20 t} d t

\int \frac{1}{3} sin (3 x) + 2 d x

\int \frac{14}{1 - x ^{2}} d x
