I know I shouldn't be asking.
Gah, Maths is so pointless, but I'm stuck with it until January. Can anybody help me out?
I've got to Show that:
a) (1-cos²t)(1+cotan²t)=1
b) tanθ + cotanθ = 1/ cosθsinθ
c) sinθtanθ+cosθ = secant θ
I don't need to solve the equations or find any values, I've just got to show the statements are true. I don't know where to start with these three buggers.
Anybody? Pointless trig is my main sticking point. Any ideas?
