integral of e^{a*x}

\int e^{a \cdot x} d x

\frac{1}{a} e^{a x} + C

Solution steps

\int e^{a x} d x

Apply u-substitution

: \int \frac{e ^{u}}{a} d u

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

Take the constant out:

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

= \frac{1}{a} \cdot \int e^{u} d u

Use the common integral:

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

= \frac{1}{a} e^{u}

Substitute back

u = a x

= \frac{1}{a} e^{a x}

Add a constant to the solution

= \frac{1}{a} e^{a x} + C

\int \frac{3 x ^{2} - 5 x + 1}{2 x + 1} d x

\int (t + 5)^{2} 3 - t d t

\int 4 cos (t) sin (t) d t

\int \frac{1}{( x ^{2} + 2 ) ^{3}} d x

\int \frac{x}{cos ( x ) + 1} d x
