integral of 2-2tan^2(x)

\int 2 - 2 tan^{2} (x) d x

4 x - 2 tan (x) + C

Solution steps

\int 2 - 2 tan^{2} (x) d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

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

\int 2 d x = 2 x

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

= 2 x - 2 (- x + tan (x))

Simplify

2 x - 2 (- x + tan (x)) : 4 x - 2 tan (x)

= 4 x - 2 tan (x)

Add a constant to the solution

= 4 x - 2 tan (x) + C

\int \frac{2 y ^{4}}{y ^{5} + 1} d y

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

\int (x^{2} + 9)^{2} d x

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

\int \frac{x ^{2} - 4}{x ^{3} - 12 x + 9} d x
