I have: -2sin(t)+ cos(t) =0
How can I find out what t is?
I dont even know how to start, because I havent done this in over 3 years..
Help would be appreciated!
there are infinitely many solutions, not just 2--not unless the problem itself tells you to restrict your answer.
Hint 1: tangent is periodic.
Hint 2: tangent takes on positive values in the first and third quadrants. arctan(1/2) is in the first quadrant. apply what you know of reference angles.
