Question

Consider the curve C parametrized by (x, y) = (5 cos (−12t), 5 sin(−12t)), for −π/2 ≤ t ≤ π/2

Then C is a circle of radius ____, and is traversed ____ times in the ____ direction.

Answer 1

5,12t ,negative I guess

Answer 2

the radius is the coefficient then?

Answer 3

rcos(x) +rsin(x)
standard equation

Answer 4

awesome, thank you! for the number of times traversed I ended up writing 6 because of the intervals (pi/2). does that make sense?

Answer 5

idk what you are saying

Answer 6

Circle C traverses 6 times, right?
