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

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

\frac{1}{2}

Decimal Notation

0.5

Solution steps

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

Plug in the value

x = - 1

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

1 + (- 1)^{2} = 2

= \frac{1}{2}

arcsin (9 x + 1)

\int \frac{1}{x ^{\frac{4}{5}}} d x

\int_{2}^{\infty} \frac{1}{x} d x

\int - 2.5 - \frac{1}{8} q d q

\frac{d}{d x} (e^{s e c (x^{2})})
