derivative of

1 + cos^{2} (x)

- sin (2 x)

Solution steps

\frac{d}{d x} (1 + cos^{2} (x))

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (1) + \frac{d}{d x} (cos^{2} (x))

\frac{d}{d x} (1) = 0

\frac{d}{d x} (cos^{2} (x)) = - sin (2 x)

= 0 - sin (2 x)

Simplify

= - sin (2 x)

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

f (x) = \frac{2}{5 x + 3}

n = 1 \sum \infty \frac{( - 1 ) ^{n - 1}}{4 n + 1}

\frac{d}{d x} ((3 x - 2)^{2} (2 x + 1)^{4})

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