integral of ((sqrt(x)-5)^2)/(x^3)

\int \frac{( x - 5 ) ^{2}}{x ^{3}} d x

- \frac{1}{x} + \frac{20}{3 x ^{\frac{3}{2}}} - \frac{25}{2 x ^{2}} + C

Solution steps

\int \frac{( x - 5 ) ^{2}}{x ^{3}} d x

Expand

\frac{( x - 5 ) ^{2}}{x ^{3}} : \frac{1}{x ^{2}} - \frac{10}{x ^{\frac{5}{2}}} + \frac{25}{x ^{3}}

= \int \frac{1}{x ^{2}} - \frac{10}{x ^{\frac{5}{2}}} + \frac{25}{x ^{3}} 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

= \int \frac{1}{x ^{2}} d x - \int \frac{10}{x ^{\frac{5}{2}}} d x + \int \frac{25}{x ^{3}} d x

\int \frac{1}{x ^{2}} d x = - \frac{1}{x}

\int \frac{10}{x ^{\frac{5}{2}}} d x = - \frac{20}{3 x ^{\frac{3}{2}}}

\int \frac{25}{x ^{3}} d x = - \frac{25}{2 x ^{2}}

= - \frac{1}{x} - (- \frac{20}{3 x ^{\frac{3}{2}}}) - \frac{25}{2 x ^{2}}

Simplify

= - \frac{1}{x} + \frac{20}{3 x ^{\frac{3}{2}}} - \frac{25}{2 x ^{2}}

Add a constant to the solution

= - \frac{1}{x} + \frac{20}{3 x ^{\frac{3}{2}}} - \frac{25}{2 x ^{2}} + C

\frac{d}{d x} (\frac{1}{x - ( x ^{2} - 1 ) ^{\frac{1}{2}}})

f (x) = 1100 (x^{2} - 0.2 x)

3 x^{2} + 6, y = 6.4, y = 8.1

y = - 2 sin (x), at x = \frac{3}{4} π

\frac{d}{d x} (\frac{cos ( x )}{1 + cos ( x )})
