Can you please help me verify the identity: (sin(5x)/sin(x)) - (cos(5x)/cos(x)) = 4cos2x?

To continue alex's answer 4x^2 - 5x + 2 = 2x - 1 4x^2 - 7x + 3 = 0 (x - 1)(4x - 3) = 0 Now it should be really easy!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
