integral of (3x+5)e^{3x+5}

\int (3 x + 5) e^{3 x + 5} d x

e^{5} (e^{3 x} x + \frac{4}{3} e^{3 x}) + C

Solution steps

\int (3 x + 5) e^{3 x + 5} d x

(3 x + 5) e^{3 x + 5} = e^{5} (3 x + 5) e^{3 x}

= \int e^{5} (3 x + 5) e^{3 x} d x

Take the constant out:

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

= e^{5} \cdot \int (3 x + 5) e^{3 x} d x

Apply Integration By Parts

: e^{3 x} x + \frac{5}{3} e^{3 x} - \int e^{3 x} d x

= e^{5} (e^{3 x} x + \frac{5}{3} e^{3 x} - \int e^{3 x} d x)

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

= e^{5} (e^{3 x} x + \frac{5}{3} e^{3 x} - \frac{1}{3} e^{3 x})

Add similar elements:

\frac{5}{3} e^{3 x} - \frac{1}{3} e^{3 x} = \frac{4}{3} e^{3 x}

= e^{5} (e^{3 x} x + \frac{4}{3} e^{3 x})

Add a constant to the solution

= e^{5} (e^{3 x} x + \frac{4}{3} e^{3 x}) + C

\int cos (πn x) d x

\frac{d y}{d x} = 4 cos (x) (3 + 2 y)^{2}

\int_{- 2}^{3} 2 x d x

\frac{d}{d x} (\frac{x + 1}{x - 1})

x \to 0 lim (cos (x))
