Sec(a-b) = cos(a+b) / cos^2a - sin^2b I'm trying to prove this, by turning the left side into the right. I am stuck. Presumably you have already done the sum and difference formulas for sin and cos.

Two American high school students have stunned mathematicians after they claimed that they discovered a new way to prove Pythagoras' theorem by using trigonometry- a feat mathematicians thought was ...
