(\partial)/(\partial x)(rcos(x))

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

- r sin (x)

Solution steps

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

Treat

r

as a constant

Take the constant out:

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

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

Apply the common derivative:

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

= r (- sin (x))

Simplify

= - r sin (x)

x \to 7 lim (3 x - 4)

\frac{\partial}{\partial x} (\frac{x ^{4}}{x ^{2} + y ^{2}})

\int 2 x 1 - x^{2} d x

\int \frac{1}{- x ^{2} - 8 x - 7} d x

\frac{d}{d x} ((sec (x))^{2})
