derivative of

y (θ) = \frac{π}{9} cos (θ)

- \frac{π}{9} sin (θ)

Solution steps

\frac{d}{d θ} (\frac{π}{9} cos (θ))

Take the constant out:

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

= \frac{π}{9} \frac{d}{d θ} (cos (θ))

Apply the common derivative:

\frac{d}{d θ} (cos (θ)) = - sin (θ)

= \frac{π}{9} (- sin (θ))

Simplify

= - \frac{π}{9} sin (θ)

x \to 0 lim (\frac{1}{x ^{2} + x})

\int - \frac{8}{y ^{9}} d y

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

y = x^{2} - 1, y = - x + 2, x = 0, x = 1

\int \frac{3}{x ^{4}} + 2 - \frac{3}{x ^{2}} d x
