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

simplify

\frac{2}{1 + tan ^{2} ( x )}

2 cos (x)

Solution steps

\frac{2}{1 + tan ^{2} ( x )}

Rewrite using trig identities

= \frac{2}{sec ^{2} ( x )}

Express with sin, cos

= 2 cos^{2} (x)

cos^{2} (x) = cos (x)

= 2 cos (x)

sin (4 t + \frac{π}{3})

cos (2 t - π)

cos (\frac{3 π}{2} - θ)

sec (θ - 18 0^{\circ})

cos (- α)
