simplify 1/((cos^2(x)+4sin^2(x)))

simplify

\frac{1}{( cos ^{2} ( x ) + 4 sin ^{2} ( x ) )}

\frac{1}{3 sin ^{2} ( x ) + 1}

Solution steps

\frac{1}{cos ^{2} ( x ) + 4 sin ^{2} ( x )}

Simplify

cos^{2} (x) + 4 sin^{2} (x) : 3 sin^{2} (x) + 1

= \frac{1}{3 sin ^{2} ( x ) + 1}

(\frac{1}{x} - \frac{y}{3})^{3}

(2 a + 1) (\frac{1}{2} a - \frac{1.2}{4} a^{2} - 1)

\frac{4}{9} a^{4} - \frac{25}{4}

(2 r)^{- 7}

9 x^{2} - 9 x y - 4 y^{2}
