integral of sqrt((5+x)/(5-x))

\int \frac{5 + x}{5 - x} d x

- x + 5 5 - x + 10 arctan (\frac{x + 5}{5 - x}) + C

Solution steps

\int \frac{5 + x}{5 - x} d x

Apply u-substitution

: \int - \frac{- u + 10}{u} d u

= \int - \frac{- u + 10}{u} d u

Take the constant out:

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

= - \int \frac{- u + 10}{u} d u

Expand

\frac{- u + 10}{u} : - 1 + \frac{10}{u}

= - \int - 1 + \frac{10}{u} d u

Apply u-substitution

: \int - \frac{10 v - 1}{v ^{2}} d v

= - \int - \frac{10 v - 1}{v ^{2}} d v

Take the constant out:

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

= - (- 10 \cdot \int \frac{v - 1}{v ^{2}} d v)

Apply Integration By Parts

: - \frac{v - 1}{v} - \int - \frac{1}{2 v v - 1} d v

= - (- 10 (- \frac{v - 1}{v} - \int - \frac{1}{2 v v - 1} d v))

Take the constant out:

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

= - (- 10 (- \frac{v - 1}{v} - (- \frac{1}{2} \cdot \int \frac{1}{v v - 1} d v)))

Apply u-substitution

: \int \frac{2}{w ^{2} + 1} d w

= - (- 10 (- \frac{v - 1}{v} - (- \frac{1}{2} \cdot \int \frac{2}{w ^{2} + 1} d w)))

Take the constant out:

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

= - (- 10 (- \frac{v - 1}{v} - (- \frac{1}{2} \cdot 2 \cdot \int \frac{1}{w ^{2} + 1} d w)))

Use the common integral:

\int \frac{1}{w ^{2} + 1} d w = arctan (w)

= - (- 10 (- \frac{v - 1}{v} - (- \frac{1}{2} \cdot 2 arctan (w))))

Substitute back

= - - 10 - \frac{\frac{10}{5 - x} - 1}{\frac{10}{5 - x}} - (- \frac{1}{2} \cdot 2 arctan (\frac{10}{5 - x} - 1))

Simplify

- - 10 - \frac{\frac{10}{5 - x} - 1}{\frac{10}{5 - x}} - (- \frac{1}{2} \cdot 2 arctan (\frac{10}{5 - x} - 1)) : - x + 5 5 - x + 10 arctan (\frac{x + 5}{5 - x})

= - x + 5 5 - x + 10 arctan (\frac{x + 5}{5 - x})

Add a constant to the solution

= - x + 5 5 - x + 10 arctan (\frac{x + 5}{5 - x}) + C

\frac{\partial}{\partial x} (x^{3} e^{2 x y})

\int \frac{1}{x lo g _{e} ( x )} d x

f (x) = 2 x^{2} - 5 x + 3, a = 1

y^{^{'}} = \frac{y}{t} - (\frac{y}{t})^{2}

f (x) = x^{3} e^{- 2 x}
