How do you simplify this? The first part is the answer to something, but I don\'t get how it is simplified... Solution Multiply the numerator and denominator with 4 (4*(cos2/2)-4(sin2/4))/(-4(sin2/2)- 4(cos2/4)) =(2cos2-sin2)/(-2sin2-cos2) Multiply the numerator and denominator with -1 =(sin2- 2cos2)/(2sin2+cos2) Divide the numerator and denominator by cos2 (sin2/cos2- 2cos2/cos2)/(2sin2/cos2-cos2/cos2) =(tan2-2)/(2tan2+1).
