Answer 3

what do you want exactly?

Answer 4

How did you get to that, please explain?

Answer 5

ok I try to explain sorry for poor english I may have difficulty.
imagine the Trigonometric circle: when you say x+pi you go after pi(180) or the third part of the circle.in that part the sign of cos is always NEGATIVE.
so the result of cos(x+pi) is negative!
I hope you get it =) again sorry for my poor english!
