limit as x approaches-2 of 4^xcos(pix)

x \to - 2 lim (4^{x} cos (π x))

\frac{1}{16}

Decimal

0.0625

Solution steps

x \to - 2 lim (4^{x} cos (π x))

Plug in the value

x = - 2

= 4^{- 2} cos (π (- 2))

Simplify

4^{- 2} cos (π (- 2)) : \frac{1}{16}

= \frac{1}{16}

e^{3 x^{3}}

y = x (x - 8)

2^{3 x + 1}

\frac{d}{d r} (\frac{r}{r ^{2} + 1})

f (x) = x \cdot 5^{x}, at x = 1
