integral of-5e^{cos(x)}sin(x)

\int - 5 e^{c o s (x)} sin (x) d x

5 e^{c o s (x)} + C

Solution steps

\int - 5 e^{c o s (x)} sin (x) d x

Take the constant out:

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

= - 5 \cdot \int e^{c o s (x)} sin (x) d x

Apply u-substitution

: \int - e^{u} d u

= - 5 \cdot \int - e^{u} d u

Take the constant out:

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

= - 5 (- \int e^{u} d u)

Use the common integral:

\int e^{u} d u = e^{u}

= - 5 (- e^{u})

Substitute back

u = cos (x)

= - 5 (- e^{c o s (x)})

Simplify

= 5 e^{c o s (x)}

Add a constant to the solution

= 5 e^{c o s (x)} + C

\int 3 e^{x} + 3 d x

\int \frac{4 x}{5 ( 6 x ^{2} - 7 ) ^{\frac{2}{3}}} d x

\int 6 - 2 x d x

\int 3 sin (θ) d θ

\int \frac{3}{36 - 16 x ^{2}} d x
