(\partial)/(\partial s)(rcos(s))

\frac{\partial}{\partial s} (r cos (s))

- r sin (s)

Solution steps

\frac{\partial}{\partial s} (r cos (s))

Treat

r

as a constant

Take the constant out:

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

= r \frac{\partial}{\partial s} (cos (s))

Apply the common derivative:

\frac{\partial}{\partial s} (cos (s)) = - sin (s)

= r (- sin (s))

Simplify

= - r sin (s)

\frac{x ( 11 - x )}{1100} d x = d t, x (0) = 3

f (x) = 8

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

\int \frac{x ^{4} + 1}{2 x ^{2}} d x

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