integral of 2(sec(x))^2

\int 2 (sec (x))^{2} d x

2 tan (x) + C

Solution steps

\int 2 (sec (x))^{2} d x

Take the constant out:

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

= 2 \cdot \int (sec (x))^{2} d x

Simplify

= 2 \cdot \int sec^{2} (x) d x

Use the common integral:

\int sec^{2} (x) d x = tan (x)

= 2 tan (x)

Add a constant to the solution

= 2 tan (x) + C

\frac{\partial ^{2}}{\partial y ^{2}} (y^{4} sin (6 x))

\int (2 x + 7)^{\frac{3}{2}} d x

f (x) = \frac{x}{5} + \frac{7}{x}

\frac{d}{d x} (\frac{a x - 4 1 + x}{x ^{2} - 1})

n = 1 \sum \infty (\frac{1}{e})^{n}
