Solución detallada
Tenemos la ecuación
cos⁡(x)=c+2\cos{\left(x \right)} = c + 2
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
x=πn+acos⁡(c+2)x = \pi n + \operatorname{acos}{\left(c + 2 \right)}
x=πn+acos⁡(c+2)−πx = \pi n + \operatorname{acos}{\left(c + 2 \right)} - \pi
O
x=πn+acos⁡(c+2)x = \pi n + \operatorname{acos}{\left(c + 2 \right)}
x=πn+acos⁡(c+2)−πx = \pi n + \operatorname{acos}{\left(c + 2 \right)} - \pi
, donde n es cualquier número entero

x1=−re⁡(acos⁡(c+2))−iim⁡(acos⁡(c+2))+2πx_{1} = - \operatorname{re}{\left(\operatorname{acos}{\left(c + 2 \right)}\right)} - i \operatorname{im}{\left(\operatorname{acos}{\left(c + 2 \right)}\right)} + 2 \pi 
x2 = I*im(acos(2 + c)) + re(acos(2 + c))
x2=re⁡(acos⁡(c+2))+iim⁡(acos⁡(c+2))x_{2} = \operatorname{re}{\left(\operatorname{acos}{\left(c + 2 \right)}\right)} + i \operatorname{im}{\left(\operatorname{acos}{\left(c + 2 \right)}\right)} 
x2 = re(acos(c + 2)) + i*im(acos(c + 2))
