integral of 6+6tan^2(x)

\int 6 + 6 tan^{2} (x) d x

6 tan (x) + C

Solution steps

\int 6 + 6 tan^{2} (x) d x

6 + 6 tan^{2} (x) = 6 (1 + tan^{2} (x))

= \int 6 (1 + tan^{2} (x)) d x

Take the constant out:

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

= 6 \cdot \int 1 + tan^{2} (x) d x

Rewrite using trig identities

= 6 \cdot \int sec^{2} (x) d x

Use the common integral:

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

= 6 tan (x)

Add a constant to the solution

= 6 tan (x) + C

\int - 7 d x

\int_{0}^{1} \frac{x ^{2}}{x ^{3} - 5} d x

\int \frac{x ^{3}}{x ^{2} + 121} d x

f (x) = \frac{1}{x ^{2} - 5}

\int sin (22 x) sin (23 x) d x
