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

expand

\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}}

(3 + \frac{i}{n})^{2}

tan (θ) cos (θ)

\frac{( 1 - 2 x ) ^{7}}{x ^{4}}

(- 17, - 11) y (13, 7) l e f t (- 7, 4)

\frac{x ^{5} y ^{6}}{x y ^{2}}
