integral of ((e^{3x}))/3

\int \frac{( e ^{3 x} )}{3} d x

\frac{1}{9} e^{3 x} + C

Solution steps

\int \frac{e ^{3 x}}{3} d x

Take the constant out:

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

= \frac{1}{3} \cdot \int e^{3 x} d x

Apply u-substitution

= \frac{1}{3} \cdot \int e^{u} \frac{1}{3} d u

Take the constant out:

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

= \frac{1}{3} \cdot \frac{1}{3} \cdot \int e^{u} d u

Use the common integral:

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

= \frac{1}{3} \cdot \frac{1}{3} e^{u}

Substitute back

u = 3 x

= \frac{1}{3} \cdot \frac{1}{3} e^{3 x}

Simplify

\frac{1}{3} \cdot \frac{1}{3} e^{3 x} : \frac{1}{9} e^{3 x}

= \frac{1}{9} e^{3 x}

Add a constant to the solution

= \frac{1}{9} e^{3 x} + C

\int 5 x x - 9 d x

\int x^{2} - 4 x + 2 d x

\int \frac{1}{b} e^{- \frac{x}{b}} d x

\int - 1 + 2 cos^{2} (2 t) d t

\int (x^{\frac{1}{3}} - x + 9) d x
