(2cos^2(x))/(2(1-sin(x))-cos^2(x))=0

Solución

\frac{2 cos ^{2} ( x )}{2 ( 1 - sin ( x ) ) - cos ^{2} ( x )} = 0

x = \frac{3 π}{2} + 2 πn

Grados

x = 27 0^{\circ} + 36 0^{\circ} n

Pasos de solución

\frac{2 cos ^{2} ( x )}{2 ( 1 - sin ( x ) ) - cos ^{2} ( x )} = 0

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

x = \frac{π}{2} + 2 πn, x = \frac{3 π}{2} + 2 πn

Siendo que la ecuación esta indefinida para:

\frac{π}{2} + 2 πn

x = \frac{3 π}{2} + 2 πn

2 sin (x) = - 3

tan (θ) = \frac{- 12}{5}, cot (θ)

3 cos (1 x) = - sin (1 x)

0 = 3 cos (θ)

1 - 3 sin^{2} (x) = cos^{2} (x) - sin^{2} (x)
