limit as x approaches 1 of (x^2-1)/(x-1)

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

2

Solution steps

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

Simplify

\frac{x ^{2} - 1}{x - 1} : x + 1

= x \to 1 lim (x + 1)

Plug in the value

x = 1

= 1 + 1

Simplify

= 2

\int \frac{y}{3} d y

\int \frac{e ^{x} x}{x ^{2}} d x

\int_{0}^{1} \frac{10 y}{e ^{2 y}} d y

\frac{d}{d x} (4 x sin (x) cos (x))

\frac{d y}{d x} = 7 x^{2} - x y
