Hello,
I am having a little problem with my trigonometry and law of cosines. The book I have explains the trigonometry but I think it is the algebra that I am having a problem with.
I have,
I would have values for "C", "B", "cosc" but not "A"
I get stuck when I don't have "A", I work out an answer where I have,
So I end up getting "2Bcosc" but not "A", the same on the other side. I think it is just something to do with rearranging.
Any help would be great thanks
