integral of e^{(4x)/9}(4/9)

\int e^{\frac{4 x}{9}} (\frac{4}{9}) d x

e^{\frac{4 x}{9}} + C

Solution steps

\int e^{\frac{4 x}{9}} \frac{4}{9} d x

Take the constant out:

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

= \frac{4}{9} \cdot \int e^{\frac{4 x}{9}} d x

Apply u-substitution

: \int e^{u} \frac{9}{4} d u

= \frac{4}{9} \cdot \int e^{u} \frac{9}{4} d u

Take the constant out:

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

= \frac{4}{9} \cdot \frac{9}{4} \cdot \int e^{u} d u

Use the common integral:

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

= \frac{4}{9} \cdot \frac{9}{4} e^{u}

Substitute back

u = \frac{4 x}{9}

= \frac{4}{9} \cdot \frac{9}{4} e^{\frac{4 x}{9}}

Simplify

\frac{4}{9} \cdot \frac{9}{4} e^{\frac{4 x}{9}} : e^{\frac{4 x}{9}}

= e^{\frac{4 x}{9}}

Add a constant to the solution

= e^{\frac{4 x}{9}} + C

x^{2} - 4 x

\frac{d}{d x} (lo g_{10} (7 x))

\int sin (\frac{1}{10}) x sin (\frac{1}{20}) x d x

x \to 4 + lim (5 x^{2} + x)

3 x \frac{d y}{d x} = 2 x e^{x} - 3 y + 6 x^{2}
