derivative of

2 x - tan (x)

2 - sec^{2} (x)

Solution steps

\frac{d}{d x} (2 x - tan (x))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (2 x) - \frac{d}{d x} (tan (x))

\frac{d}{d x} (2 x) = 2

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

= 2 - sec^{2} (x)

k = 1 \sum \infty \frac{1}{k + 6}

f (x) = \frac{3 x}{4 - x ^{2}}, at x = 1

x \to 3 lim (\frac{x ^{2} + 9}{x - 3})

x \to 7 + lim (x + 2)

\frac{\partial}{\partial x} (2 x^{\frac{2}{3}} y^{\frac{1}{3}})
