Find the travel option that best suits you. A+B+C=270° then cos2a+cos2b+cos2c+4sina sinb sinc Find the value Let's solve in different points by considering smaller units Cos2a + Cos2b = 2Cos(a+b)Cos(a-b) Join now for JEE/NEET and also prepare for Boards Join now for JEE/NEET and also prepare for Boards. Dec 20, 2016 · cos 2A + i sin 2A = cos² A + 2i sin A cos A + i²sin² A. cos 2A + i sin 2A = cos² A + 2i sin A cos A − sin² A. cos 2A + i sin 2A = (cos² A − sin² A) + i (2 sin A cos A) Since the real parts on left and right must be equal, you have the formula for cos 2A. Since the imaginary parts must be equal, you have the formula for sin 2A. That Oct 13, 2012 · cos(270+x) means you take an angle from the negative vertical.
