limit as x approaches-1 of x^3-4x+1

x \to - 1 lim (x^{3} - 4 x + 1)

4

Solution steps

x \to - 1 lim (x^{3} - 4 x + 1)

Plug in the value

x = - 1

= (- 1)^{3} - 4 (- 1) + 1

Simplify

(- 1)^{3} - 4 (- 1) + 1 : 4

= 4

n = 10000 \sum \infty \frac{1}{n}

\int \frac{x - arctan ( 2 x )}{1 + 4 x ^{2}} d x

\frac{d}{d x} (cos (x) + cos (y))

\frac{d}{d x} (\frac{x}{3 + x})
