Answer:
t0 = π/4
Step-by-step explanation:
The velocity v(t) = r'(t) = <-2sint,-2cost>
Since <1,-1>⊥v, <1,-1>•v=0. So,
(1)(-2sint) + (-1)(-2cost) = 0
cost - sint = 0

Trapezoids are quadrilaterals with one pair of parallel lines, not two. A rectangle has two pairs of parallel lines and is congruent. Therefore, it is not a rectangle.
