Find (a) sin ∅, (b) cos ∅, and (c) tan ∅ for the given quadrantal angle. If the value is undefined, write “undefined.” My quadrantal angle is -450°
Sin = opp/hyp
Cos= adj/hyp
Tan= opp/adj
I drew a graph and put the angle -450° in the 3rd quadrant because both x and y are negative and I assumed since my degree is in negative it would have to be in there. I am stuck on how to actually solve the problem. My teacher gave us the answers but we have to show our work, it is just very confusing because he isn't good at explaining at all so I am lost.
Please help me figure out how to solve this problem!
