derivative of cos(7pix)

Lösung

\frac{d}{d x} (cos (7 π x))

- sin (7 π x) \cdot 7 π

Schritte zur Lösung

\frac{d}{d x} (cos (7 π x))

Wende die Kettenregel an:

- sin (7 π x) \frac{d}{d x} (7 π x)

= - sin (7 π x) \frac{d}{d x} (7 π x)

\frac{d}{d x} (7 π x) = 7 π

= - sin (7 π x) \cdot 7 π

\int sin^{\frac{1}{2}} (x) cos^{3} (x) d x

n \to \infty lim (i = 1 \sum n \frac{i ^{3}}{n ^{4}} + \frac{1}{n})

\frac{d}{d x} (x cos (y) - y e^{x})

x \to 5 lim (\frac{x ^{2} - 7 x + 10}{x ^{2} - 25})

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