limit as x approaches-4 of sqrt(x^2-16)

x \to - 4 lim (x^{2} - 16)

0

Solution steps

x \to - 4 lim (x^{2} - 16)

Plug in the value

x = - 4

= (- 4)^{2} - 16

Simplify

(- 4)^{2} - 16 : 0

= 0

\frac{d}{d x} (6 sin (x) - \frac{2}{cos ( x )})

\frac{d y}{d x} = 1 - y^{2}

t an g e n t f (x) = 6 x, (6, 6)

\frac{\partial}{\partial s} (\frac{( s - 3 r )}{t})

\int x^{2} 13 x - 1 d x
