derivative of cos((pix/2))

Lösung

\frac{d}{d x} (cos (\frac{π x}{2}))

- sin (\frac{π x}{2}) \frac{π}{2}

Schritte zur Lösung

\frac{d}{d x} (cos (\frac{π x}{2}))

Wende die Kettenregel an:

- 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}

\frac{\partial}{\partial x} (6 x + 12)

t an g e n t f (x) = \frac{8}{7 x}, at 1, 87

\frac{\partial}{\partial x} (x^{6} - 4 x^{2} y^{4} + 3 y^{2})

\frac{d}{d x} ((- x^{3} + 1) (- 2 x^{2} - 2 x))

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