integral of sec^2(x)*e^{tan(x)}

\int sec^{2} (x) \cdot e^{t a n (x)} d x

e^{t a n (x)} + C

Solution steps

\int sec^{2} (x) e^{t a n (x)} d x

Apply u-substitution

: \int e^{u} d u

= \int e^{u} d u

Use the common integral:

\int e^{u} d u = e^{u}

= e^{u}

Substitute back

u = tan (x)

= e^{t a n (x)}

Add a constant to the solution

= e^{t a n (x)} + C

\int (\frac{2 x ^{2} + 9 x - 6}{x - 5}) d x

\int x^{2} cos (\frac{nπ x}{l}) d x

\int cos (e^{x}) e^{x} d x

\int 2 x^{2} e^{- 2 x} d x

\int \frac{( x + 3 )}{x ^{2} + 6 x + 10} d x
