integral of (25-x^2)^{-3/2}

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

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

Solution steps

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

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

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

Apply Trigonometric Substitution

: \int \frac{1}{25 cos ^{2} ( u )} d u

= \int \frac{1}{25 cos ^{2} ( u )} d u

Take the constant out:

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

= \frac{1}{25} \cdot \int \frac{1}{cos ^{2} ( u )} d u

Use the common integral:

\int \frac{1}{cos ^{2} ( u )} d u = tan (u)

= \frac{1}{25} tan (u)

Substitute back

u = arcsin (\frac{1}{5} x)

= \frac{1}{25} tan (arcsin (\frac{1}{5} x))

Simplify

\frac{1}{25} tan (arcsin (\frac{1}{5} x)) : \frac{x}{25 ( 25 - x ^{2} ) ^{\frac{1}{2}}}

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

Add a constant to the solution

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

\frac{d}{d x} (1 0^{2 x})

\frac{d b}{d b}

(3 x^{4} + 3 x)^{2}

n = 0 \sum \infty \frac{3}{7 ^{n}}

\frac{d}{d x} ((7 x + 1) (x^{4} - x^{3} - 9 x))
