derivative of

y (θ) = \frac{π}{7} cos (θ)

- \frac{π}{7} sin (θ)

Solution steps

\frac{d}{d θ} (\frac{π}{7} cos (θ))

Take the constant out:

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

= \frac{π}{7} \frac{d}{d θ} (cos (θ))

Apply the common derivative:

\frac{d}{d θ} (cos (θ)) = - sin (θ)

= \frac{π}{7} (- sin (θ))

Simplify

= - \frac{π}{7} sin (θ)

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

\int e^{x} sin (y) d x

\frac{d}{d x} (y^{2} - 2 y \cdot cos (x))

(1 + cos (t)) y^{^{'}} = (1 + e - y) sin (t), y (0) = 0

(x - 2)^{2} (x - 1)
