/x for 0 = 1 | <1 for 1 = 1 = 2*sin(t)*x + log(t)*y | \0 otherwise
$$\begin{cases} x & \text{for}\: 0 = 1 \\1 & \text{for}\: 1 = 1 \\0 & \text{otherwise} \end{cases} = x 2 \sin{\left(t \right)} + y \log{\left(t \right)}$$
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$\begin{cases} x & \text{for}\: 0 = 1 \\1 & \text{for}\: 1 = 1 \\0 & \text{otherwise} \end{cases} = 2 x \sin{\left(t \right)} + y \log{\left(t \right)}$$
Коэффициент при y равен
$$- \log{\left(t \right)}$$
entonces son posibles los casos para t :
$$t < 1$$
$$t = 1$$
Consideremos todos los casos con detalles:
Con
$$t < 1$$
la ecuación será
$$\tilde{\infty} y + \begin{cases} x & \text{for}\: 0 = 1 \\1 & \text{for}\: 1 = 1 \\0 & \text{otherwise} \end{cases} = 0$$
su solución
Con
$$t = 1$$
la ecuación será
