\frac{d}{d x} (29 - x^{2} - 4 y^{2})

- \frac{x + 4 y \frac{d y}{d x}}{- x ^{2} - 4 y ^{2} + 29}

Solution steps

\frac{d}{d x} (29 - x^{2} - 4 y^{2})

Apply the chain rule:

\frac{1}{2 29 - x ^{2} - 4 y ^{2}} \frac{d}{d x} (29 - x^{2} - 4 y^{2})

= \frac{1}{2 29 - x ^{2} - 4 y ^{2}} \frac{d}{d x} (29 - x^{2} - 4 y^{2})

\frac{d}{d x} (29 - x^{2} - 4 y^{2}) = - 2 x - 8 y \frac{d y}{d x}

= \frac{1}{2 29 - x ^{2} - 4 y ^{2}} (- 2 x - 8 y \frac{d y}{d x})

Simplify

\frac{1}{2 29 - x ^{2} - 4 y ^{2}} (- 2 x - 8 y \frac{d y}{d x}) : - \frac{x + 4 y \frac{d y}{d x}}{- x ^{2} - 4 y ^{2} + 29}

= - \frac{x + 4 y \frac{d y}{d x}}{- x ^{2} - 4 y ^{2} + 29}

\frac{d}{d x} (4 cos (x) sin (x))

f (x) = \frac{x ^{3} + 9}{x ^{3}}

\frac{d}{d x} (\frac{x ^{2} + 3 x}{7})

\frac{d}{d s} (\frac{s}{s ^{2} + 4})

e^{3 x} (3 cos (4 x) - 4 sin (4 x))
