# Thread: Function using law of sines and cosines

1. ## Function using law of sines and cosines

Create a function for this scenario.
Theres a car traveling at angle theta. It is traveling at say 20.55 mph. It has to travel a total of 13.5 miles. This is in quadrant 3 of a unit circle heading away from the center. I need to find a function to represent the possible different angles the car could take.

I assume that 13.5 miles is a lateral movement?

We want: $\cos(\theta)*c = 13.5$ where $c=20.55t$

This is about all I can give you. There are an infinite number of possibilities. Is there a time constraint?

Yes there is a time constraint its 30 minutes
