\frac{d}{d x} (sin (\frac{π x}{9}))

cos (\frac{π x}{9}) \frac{π}{9}

Solution steps

\frac{d}{d x} (sin (\frac{π x}{9}))

Apply the chain rule:

cos (\frac{π x}{9}) \frac{d}{d x} (\frac{π x}{9})

= cos (\frac{π x}{9}) \frac{d}{d x} (\frac{π x}{9})

\frac{d}{d x} (\frac{π x}{9}) = \frac{π}{9}

= cos (\frac{π x}{9}) \frac{π}{9}

\frac{\partial}{\partial x} (x y e^{- 8 y})

\frac{d}{d t} (4 cos (t))

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

\int \frac{1}{x ^{1.4}} d x

\int \frac{y ^{2} + 26 y + 169}{( y ^{2} + 169 ) ^{2}} d y
