integral of 1/((2y+3))

\int \frac{1}{( 2 y + 3 )} d y

\frac{1}{2} ln ∣ 2 y + 3 ∣ + C

Solution steps

\int \frac{1}{2 y + 3} d y

Apply u-substitution

: \int \frac{1}{2 u} d u

= \int \frac{1}{2 u} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{2} ln ∣ u ∣

Substitute back

u = 2 y + 3

= \frac{1}{2} ln ∣ 2 y + 3 ∣

Add a constant to the solution

= \frac{1}{2} ln ∣ 2 y + 3 ∣ + C

\int tan (x) sec^{4} (x) d x

\int \frac{9 t ^{2} - 26 t - 5}{3 t ^{2} - 5 t - 2} d t

\int cos^{5} (\frac{3}{2}) x d x

\int \frac{14 s + 14}{( s ^{2} + 1 ) ( s - 1 ) ^{3}} d s

\int \frac{e ^{4 x}}{e ^{2 x} - 1} d x
