Consider the curve given by the parametric equations z = sint, y = sin(t + sint) where -?

(15 pts.) Consider the curve given by thc parametric equations a: = Sint, y Sin(t + Sint) where 00 < t < 00. Note that it has two tangents at the origin (O, O) since both t O and t = 7r corresond to the origin. Find the equations of the two tangents to the curve at the origin.
