derivative of

f (x) = cos (\frac{π x}{2})

- sin (\frac{π x}{2}) \frac{π}{2}

Solution steps

\frac{d}{d x} (cos (\frac{π x}{2}))

Apply the chain rule:

- sin (\frac{π x}{2}) \frac{d}{d x} (\frac{π x}{2})

= - sin (\frac{π x}{2}) \frac{d}{d x} (\frac{π x}{2})

\frac{d}{d x} (\frac{π x}{2}) = \frac{π}{2}

= - sin (\frac{π x}{2}) \frac{π}{2}

\int \frac{x}{1 - x x} d x

y = (x + 3)^{2} - (x - 2)^{2}

(3, - 6), (5, - 5)

\frac{d y}{d x} = 9 x e^{y}

\int sec^{3} (7 x - 1) d x
