Solución

resolver para

y, arctan (y) + \frac{1}{2} (1 - t)^{2} = c

Solución

y = tan (c - \frac{1}{2} + t - \frac{1}{2} t^{2})

Pasos de solución

arctan (y) + \frac{1}{2} (1 - t)^{2} = c

Mover

\frac{1}{2} (1 - t)^{2}

al lado derecho

arctan (y) + \frac{1}{2} (1 - t)^{2} = c

Restar

\frac{1}{2} (1 - t)^{2}

de ambos lados

arctan (y) + \frac{1}{2} (1 - t)^{2} - \frac{1}{2} (1 - t)^{2} = c - \frac{1}{2} (1 - t)^{2}

Simplificar

arctan (y) + \frac{1}{2} (1 - t)^{2} - \frac{1}{2} (1 - t)^{2} = c - \frac{1}{2} (1 - t)^{2}
