integral of x/((x^2+25)^{1/2)}

\int \frac{x}{( x ^{2} + 25 ) ^{\frac{1}{2}}} d x

\frac{x ^{2}}{( x ^{2} + 25 ) ^{\frac{1}{2}}} + \frac{25}{( x ^{2} + 25 ) ^{\frac{1}{2}}} + C

Solution steps

\int \frac{x}{( x ^{2} + 25 ) ^{\frac{1}{2}}} d x

Apply Integration By Parts

: \frac{x ^{2}}{( x ^{2} + 25 ) ^{\frac{1}{2}}} - \int \frac{25 x}{( x ^{2} + 25 ) ^{\frac{3}{2}}} d x

= \frac{x ^{2}}{( x ^{2} + 25 ) ^{\frac{1}{2}}} - \int \frac{25 x}{( x ^{2} + 25 ) ^{\frac{3}{2}}} d x

\int \frac{25 x}{( x ^{2} + 25 ) ^{\frac{3}{2}}} d x = - \frac{25}{( x ^{2} + 25 ) ^{\frac{1}{2}}}

= \frac{x ^{2}}{( x ^{2} + 25 ) ^{\frac{1}{2}}} - (- \frac{25}{( x ^{2} + 25 ) ^{\frac{1}{2}}})

Simplify

= \frac{x ^{2}}{( x ^{2} + 25 ) ^{\frac{1}{2}}} + \frac{25}{( x ^{2} + 25 ) ^{\frac{1}{2}}}

Add a constant to the solution

= \frac{x ^{2}}{( x ^{2} + 25 ) ^{\frac{1}{2}}} + \frac{25}{( x ^{2} + 25 ) ^{\frac{1}{2}}} + C

\int_{- 5}^{3} \frac{x}{x ^{2} - 9} d x

f (x) = \frac{1 - 2 t}{3 + t}

\frac{d}{d x} (\frac{1}{10} + x e^{- x})

\frac{d}{d x} (e^{- 3 x} y)

\frac{\partial}{\partial x} (x^{0.3} y^{0.7})
