Cos I Sine So!

It is no big secret that Math and I are as far removed from each other as night is from day! But today, I was looking at my tripod lamp and wondering if I remember anything at all from my trigonometry class in high school. You can imagine my utter delight when I remembered:

Law of Sine

a / sin A = b / sin B = c / sin C

Law of Cosine

c2 = a2 + b2 – 2ab Cos C

Law of Tangents

(a – b) / (a + b) = tan [1/2 (A – B) ] / tan [1/2 (A + B) ]

I can't wait for Tapi and Anand to see this post! (Do you think they will be impressed?)
