Example 1: Toy Cars (Different Starting Positions)
A toy racecar is racing on a circular race track. The car is 2.5 feet from the center of the race track and travels in the CCW direction. However,
this racecar starts at the 12-0’clock position. 0 is the measure of the angle shown (in radians).
We need to be a little cautious in this scenario, because now 0 doesn't represent a number of radians swept out from the 3-o'clock position.
Instead, 0 represents a number of radians swept out from the 12-o'clock position.
0 = 6.28
You might feel tempted to write the expressions 2.5 cos(0) and 2.5 sin(0) to model the car's position relative to the center of the race track. Let's
check and see if these expressions work.
a. Compute 2.5 cos(0) and 2.5 sin(0) for 0
0.
о 2.5 сos(0) -
= 2.5cos(0)
Preview
o 2.5 sin(0)
2.5sin(0)
