limit as x approaches 1 of (x^2-3x+2)/(x^3-1)

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

- \frac{1}{3}

Decimal Notation

- 0.33333 \dots

Solution steps

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

Simplify

\frac{x ^{2} - 3 x + 2}{x ^{3} - 1} : \frac{x - 2}{x ^{2} + x + 1}

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

Plug in the value

x = 1

= \frac{1 - 2}{1 ^{2} + 1 + 1}

Simplify

= - \frac{1}{3}

\int \frac{3}{x ^{2} 25 - x ^{2}} d x

f (x) = \frac{2}{x + 2}

\frac{\partial}{\partial y} ((x^{2} + y) e^{\frac{y}{2}})

\int e^{- 2 x} sin (2 x) d x

\int \frac{x ^{4}}{x ^{2} + 1} d x
