integral of (sec^2(x))(1+tan(x))

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

\frac{( 1 + tan ( x ) ) ^{2}}{2} + C

Solution steps

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

Apply u-substitution

= \int u d u

Apply the Power Rule

= \frac{u ^{2}}{2}

Substitute back

u = 1 + tan (x)

= \frac{( 1 + tan ( x ) ) ^{2}}{2}

Add a constant to the solution

= \frac{( 1 + tan ( x ) ) ^{2}}{2} + C
