limit as x approaches 3 of x^2+2x-1

x \to 3 lim (x^{2} + 2 x - 1)

14

Solution steps

x \to 3 lim (x^{2} + 2 x - 1)

Plug in the value

x = 3

= 3^{2} + 2 \cdot 3 - 1

Simplify

= 14

v + x \cdot \frac{d v}{d x} = x^{2} - 1 + 2 v

b cos (x) + x^{2} sin (x)

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

\int 18 - x^{2} d x

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