Hi everybody, I have a system of trig. equation as follow:
cos(α1)-cos(α2)+cos(α3)=3/4
cos(5α1)-cos(5α2)+cos(5α3)=1/2
cos(7α1)-cos(7α2)+cos(7α3)=1/2
I need to solve α1, α2, α3 to eliminate the odd harmonics and my professor introduce me to use Mathcad v14, but i still unable to find its root.
Does anyone know it? pls help me. Thank you very much!
