integral of e^zcos(x)

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

e^{z} sin (x) + C

Solution steps

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

Take the constant out:

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

= e^{z} \cdot \int cos (x) d x

Use the common integral:

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

= e^{z} sin (x)

Add a constant to the solution

= e^{z} sin (x) + C

f (x) = - 1 - 4 x^{2}, (3, - 37)

2 y^{^{''}} + 72 y = 0

\frac{d}{d y} (ln (cos (y)))

\int \frac{1}{1 + e ^{- 2 x}} d x

\int 5 + 2 y d y
