4cos(θ)=4-4cos(θ)

Solución

4 cos (θ) = 4 - 4 cos (θ)

Solución

θ = \frac{π}{3} + 2 πn, θ = \frac{5 π}{3} + 2 πn

+1

Pasos de solución

4 cos (θ) = 4 - 4 cos (θ)

Usando el método de sustitución

cos (θ) = \frac{1}{2}

cos (θ) = \frac{1}{2} : θ = \frac{π}{3} + 2 πn, θ = \frac{5 π}{3} + 2 πn

Combinar toda las soluciones

θ = \frac{π}{3} + 2 πn, θ = \frac{5 π}{3} + 2 πn

Ejemplos populares

sin^2(x)+6sin(x)+5=0

sin^{2} (x) + 6 sin (x) + 5 = 0

cos(x)= 1/3 ,0<x< pi/2

cos (x) = \frac{1}{3}, 0 < x < \frac{π}{2}

3+2sin(θ)=3+2cos(θ)

3 + 2 sin (θ) = 3 + 2 cos (θ)

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

\frac{sin ( x )}{cos ( x )} = \frac{1}{3}

5 sin (θ) + 4 = 0
