limit as x approaches 3 of sqrt(x^2-9)

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

0

Solution steps

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

Plug in the value

x = 3

= 3^{2} - 9

Simplify

= 0

\int 3 cos (t) - 2 sin (t) d t

e^{4 t} (t^{2} + 3 t + 5)

\int (- 9 x^{2} sec (3 x^{3} + 1)) d x

\frac{d}{d x} ((4 x)^{5 x})

\int (3 x)^{2} + 2 d x
