integral of sinh^2(x)

\int sinh^{2} (x) d x

\frac{1}{2} (- x + \frac{1}{2} sinh (2 x)) + C

Solution steps

\int sinh^{2} (x) d x

Rewrite using trig identities

= \int \frac{- 1 + cosh ( 2 x )}{2} d x

Take the constant out:

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

= \frac{1}{2} \cdot \int - 1 + cosh (2 x) d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \frac{1}{2} (- \int 1 d x + \int cosh (2 x) d x)

\int 1 d x = x

\int cosh (2 x) d x = \frac{1}{2} sinh (2 x)

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

Add a constant to the solution

= \frac{1}{2} (- x + \frac{1}{2} sinh (2 x)) + C

\int_{0}^{4} x (x + 2) d x

x^{^{''}} + 5 x^{^{'}} = 7

\int \frac{4}{t + 1} d t

\frac{d}{d x} (x^{6} e^{8 x})

\int \frac{x + 2}{x ^{2} - 2 x + 10} d x
