integral of 3^{2x+1}

\int 3^{2 x + 1} d x

\frac{3 ^{1 + 2 x}}{2 ln ( 3 )} + C

Solution steps

\int 3^{2 x + 1} d x

Apply Integration By Parts

= 3^{2 x + 1} x - \int 2 ln (3) \cdot 3^{2 x + 1} x d x

\int 2 ln (3) \cdot 3^{2 x + 1} x d x = 3^{1 + 2 x} x - \frac{3 ^{1 + 2 x}}{2 ln ( 3 )}

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

Simplify

= \frac{3 ^{1 + 2 x}}{2 ln ( 3 )}

Add a constant to the solution

= \frac{3 ^{1 + 2 x}}{2 ln ( 3 )} + C

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

\int \frac{1}{( 9 x ^{2} + 4 ) ^{3}} d x

\int cos (θ) sin^{6} (θ) d θ

\int (4 - x^{3}) (7 + x^{4}) d x

\int (2 e^{x} + 4 cos (x)) d x
