yep i understand now, thanks everyone.

sorry if I am frustrating but i don't quite understand what you mean here. how does the 2 cos^2(\theta) get eliminated? what happens to the numerator when the sin(\theta) gets taken away?

i can see how you got from the first to second stage (using double angle formulae), but how did you come to the 3rd stage, can you please show me smaller steps?

a function can be created using a calculator that presumably uses least square regression techniques. from using your data (and excluding the 4 milion and 5 million data points) an exponential function of a = 60.4(0.78^s) where a = number of albums and s = sales*500000. This equation has a...

Homework Statement Show that (sin(2theta) - sin(theta)) / (cos(2theta) - cos(theta) + 1) = tan(theta) sorry if this setting out is unclear but i am not familiar with how to post math symbols and such. Homework Equations above The Attempt at a Solution I have tried simplifying...
