integral of 2*sin(x)

\int 2 \cdot sin (x) d x

- 2 cos (x) + C

Solution steps

\int 2 sin (x) d x

Take the constant out:

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

= 2 \cdot \int sin (x) d x

Use the common integral:

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

= 2 (- cos (x))

Simplify

= - 2 cos (x)

Add a constant to the solution

= - 2 cos (x) + C

\int_{0}^{16} \frac{9 e ^{x}}{x} d x

\int (- \frac{1}{5} sec (1 - 5 x)) d x

\int 6 x (4 x^{2} + 8)^{10} d x

(- 1, 3), (4, 1)

x \to 1 lim ((ln (x))^{1 - x})
