RE: Solve a quadratic with trigonometric values in degrees
Thanks everyone, especially you Carsen. That is a good explanation of how the CAS get used. I know this problem shouldn't need the CAS or any fancy calculator to solve this problem but I can't spend my meek brain power on solving the algebra when exam day is here. I spend too much time on it and if I have a tool in front of me that'll save me that time I just need to know how to use it on whatever comes up.
How do you get multiple answers from the equation solver in the case that there are multiple answers?
