Solución detallada
Tenemos la ecuación:
$$x = 2 \left(\log{\left(\tan{\left(\frac{t}{2} \right)} \right)} + \cos{\left(t \right)}\right)$$
cambiamos:
$$x = 2 \log{\left(\tan{\left(\frac{t}{2} \right)} \right)} + 2 \cos{\left(t \right)}$$
Abrimos los paréntesis en el miembro derecho de la ecuación
x = 2*cost + 2*logtan+t/2)
Obtenemos la respuesta: x = 2*cos(t) + 2*log(tan(t/2))
