integral of xcosh(x^2)sinh(x^2)

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

\frac{1}{8} cosh (2 x^{2}) + C

Solution steps

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

Rewrite using trig identities

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

Apply u-substitution

: \int \frac{sinh ( u )}{4} d u

= \frac{1}{2} \cdot \int \frac{sinh ( u )}{4} d u

Take the constant out:

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

= \frac{1}{2} \cdot \frac{1}{4} \cdot \int sinh (u) d u

Use the common integral:

\int sinh (u) d u = cosh (u)

= \frac{1}{2} \cdot \frac{1}{4} cosh (u)

Substitute back

u = 2 x^{2}

= \frac{1}{2} \cdot \frac{1}{4} cosh (2 x^{2})

Simplify

\frac{1}{2} \cdot \frac{1}{4} cosh (2 x^{2}) : \frac{1}{8} cosh (2 x^{2})

= \frac{1}{8} cosh (2 x^{2})

Add a constant to the solution

= \frac{1}{8} cosh (2 x^{2}) + C

\int \frac{x + 5}{2 x ^{3} - 18 x} d x

\int - \frac{2}{sin ( x )} d x

\int 6 csc^{2} (3 x) d x

\int \frac{324}{x ^{3} - 18 x ^{2}} d x

\int \frac{cos ^{2} ( 2 θ )}{sin ^{4} ( 2 θ )} d θ
