integral of (4x-2sec^2(x))

\int (4 x - 2 sec^{2} (x)) d x

2 x^{2} - 2 tan (x) + C

Solution steps

\int 4 x - 2 sec^{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 4 x d x - \int 2 sec^{2} (x) d x

\int 4 x d x = 2 x^{2}

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

= 2 x^{2} - 2 tan (x)

Add a constant to the solution

= 2 x^{2} - 2 tan (x) + C
