integral of (2cosh(sqrt(x)))/(sqrt(x))

\int \frac{2 cosh ( x )}{x} d x

4 sinh (x) + C

Solution steps

\int \frac{2 cosh ( x )}{x} d x

Take the constant out:

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

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

Apply u-substitution

: \int 2 cosh (u) d u

= 2 \cdot \int 2 cosh (u) d u

Take the constant out:

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

= 2 \cdot 2 \cdot \int cosh (u) d u

Use the common integral:

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

= 2 \cdot 2 sinh (u)

Substitute back

u = x

= 2 \cdot 2 sinh (x)

Simplify

= 4 sinh (x)

Add a constant to the solution

= 4 sinh (x) + C

\frac{d}{d x} (\frac{sin ( ln ( x ) )}{x})

\frac{\partial}{\partial x} (arctan (x^{2}))

\frac{25 - x ^{2}}{4 x}

4 x - x^{2}, x^{2}

\int 1500 + \frac{3}{2} x + \frac{3}{10} x^{2} + \frac{4}{3} x^{3} d x
