Hi, I recall that when you use the cosine rule you can sometimes come out with 2 answers (somthing to do with cos graph?). I can't qutie remeber and I've looked through my books and I can't find it. I can use the rule to calculate one side or angle, but when do you get 2 answers? Can someone please explain.
Thankyou
:)
