derivative of

25 cos (\frac{π x}{50})

- \frac{π}{2} sin (\frac{π x}{50})

Solution steps

\frac{d}{d x} (25 cos (\frac{π x}{50}))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 25 \frac{d}{d x} (cos (\frac{π x}{50}))

Apply the chain rule:

- sin (\frac{π x}{50}) \frac{d}{d x} (\frac{π x}{50})

= - sin (\frac{π x}{50}) \frac{d}{d x} (\frac{π x}{50})

\frac{d}{d x} (\frac{π x}{50}) = \frac{π}{50}

= 25 (- sin (\frac{π x}{50}) \frac{π}{50})

Simplify

25 (- sin (\frac{π x}{50}) \frac{π}{50}) : - \frac{π}{2} sin (\frac{π x}{50})

= - \frac{π}{2} sin (\frac{π x}{50})

\int cos^{3} (a x + b) d x

x \to \infty lim (e^{2})

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

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