derivative of

x - cos (x)

1 + sin (x)

Solution steps

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

Apply the Sum/Difference Rule:

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

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

\frac{d x}{d x} = 1

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

= 1 - (- sin (x))

Simplify

= 1 + sin (x)

\int_{0}^{2} 6 t d t

\frac{\partial}{\partial x} (\frac{1}{x - 3})

\frac{\partial}{\partial x} ((2 x - 3 y)^{3})

n = 1 \sum \infty \frac{x ^{2 n}}{n !}

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