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

Solución

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

Solución

x = 0.54408 \dots + 2 πn - \frac{π}{4}, x = π - 0.54408 \dots + 2 πn - \frac{π}{4}

Grados

x = - 13.82604 \dots^{\circ} + 36 0^{\circ} n, x = 103.82604 \dots^{\circ} + 36 0^{\circ} n

Pasos de solución

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

Restar

3 - sin (x)

de ambos lados

1 + cos (x) - 3 + sin (x) = 0

Re-escribir usando identidades trigonométricas

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

sin (x) + cos (x) = 2 sin (x + \frac{π}{4})

sin (x) + cos (x)

Reescribir como

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

Utilizar la siguiente identidad trivial:

cos (\frac{π}{4}) = \frac{1}{2}

Utilizar la siguiente identidad trivial:

sin (\frac{π}{4}) = \frac{1}{2}

= 2 (cos (\frac{π}{4}) sin (x) + sin (\frac{π}{4}) cos (x))

Utilizar la identidad de suma de ángulos:

sin (s + t) = sin (s) cos (t) + cos (s) sin (t)

= 2 sin (x + \frac{π}{4})

= 1 - 3 + 2 sin (x + \frac{π}{4})

1 - 3 + 2 sin (x + \frac{π}{4}) = 0
