derivative of sqrt(r^2-15x^2)

Solution

derivative of

r^{2} - 15 x^{2}

Solution

- \frac{15 x}{r ^{2} - 15 x ^{2}}

Solution steps

\frac{d}{d x} (r^{2} - 15 x^{2})

Apply the chain rule:

\frac{1}{2 r ^{2} - 15 x ^{2}} \frac{d}{d x} (r^{2} - 15 x^{2})

= \frac{1}{2 r ^{2} - 15 x ^{2}} \frac{d}{d x} (r^{2} - 15 x^{2})

\frac{d}{d x} (r^{2} - 15 x^{2}) = - 30 x

= \frac{1}{2 r ^{2} - 15 x ^{2}} (- 30 x)

Simplify

\frac{1}{2 r ^{2} - 15 x ^{2}} (- 30 x) : - \frac{15 x}{r ^{2} - 15 x ^{2}}

= - \frac{15 x}{r ^{2} - 15 x ^{2}}
