\frac{d}{d x} (cos (x) tan (x))

cos (x)

Solution steps

\frac{d}{d x} (cos (x) tan (x))

Simplify

cos (x) tan (x) : sin (x)

= \frac{d}{d x} (sin (x))

Apply the common derivative:

\frac{d}{d x} (sin (x)) = cos (x)

= cos (x)

f (x) = \frac{x}{1 + x ^{2}}, (2, \frac{2}{5})

\frac{1}{6} y^{3} + \frac{1}{2 y}

n = 1 \sum \infty \frac{n}{4 n + 1}

\frac{\partial}{\partial y} (x^{3} - y^{3} + 6 x y)

\frac{d}{d x} (x y^{2} - x^{3} y) = 0
