integral of 4e^{3x}

\int 4 e^{3 x} d x

\frac{4}{3} e^{3 x} + C

Solution steps

\int 4 e^{3 x} d x

Take the constant out:

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

= 4 \cdot \int e^{3 x} d x

Apply u-substitution

: \int e^{u} \frac{1}{3} d u

= 4 \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

= 4 \cdot \frac{1}{3} \cdot \int e^{u} d u

Use the common integral:

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

= 4 \cdot \frac{1}{3} e^{u}

Substitute back

u = 3 x

= 4 \cdot \frac{1}{3} e^{3 x}

Simplify

4 \cdot \frac{1}{3} e^{3 x} : \frac{4}{3} e^{3 x}

= \frac{4}{3} e^{3 x}

Add a constant to the solution

= \frac{4}{3} e^{3 x} + C

4 y^{^{''}} - y^{^{'}} + 1 = 0

t \to \infty lim (sin (t))

\int x^{4} ln (x^{2}) d x

f (x) = \frac{3 x - 1}{x + 2}
