how to solve this equation using mathcad or Newton-Raphson

[baby84]

cos(5Θ1)+cos(5Θ2)+cos(5Θ3)+cos(5Θ4)+cos(5Θ5)=0

cos(7Θ1)+cos(7Θ2)+cos(7Θ3)+cos(7Θ4)+cos(7Θ5)=0

cos(11Θ1)+cos(11Θ2)+cos(11Θ3)+cos(11Θ4)+cos(11Θ5)=0

cos(13Θ1)+cos(13Θ2)+cos(13Θ3)+cos(13Θ4)+cos(13Θ5)=0

cos(Θ1)+cos(Θ2)+cos(Θ3)+cos(Θ4)+cos(Θ5)=5×0.8=4

Re: how to solve this equation using mathcad or Newton-Raphs

i can't understand your problem.
what's the meaning of cos(5Θ1)?
