simplify 1/(sqrt(1+x^2))

simplify

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

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

Solution steps

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

Multiply by the conjugate

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

= \frac{1 \cdot 1 + x ^{2}}{1 + x ^{2} 1 + x ^{2}}

1 \cdot 1 + x^{2} = 1 + x^{2}

1 + x^{2} 1 + x^{2} = 1 + x^{2}

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