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

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

\frac{1}{e}

Decimal

0.36787 \dots

Solution steps

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

Apply exponent rules

= x \to 1 lim (e^{\frac{2}{1 - x ^{2}} l n (x)})

Apply the Limit Chain Rule:

\frac{1}{e}

= \frac{1}{e}
