Question

if cos &beta;+cos2&beta;+cos3&beta;=1&sin6&beta;=a+bsin2&beta;=csin4&beta; find a+b+c 2,3,4,6 are in power..

Saurabh Koranglekar · Answer

Dear student

x^3 + x^2 + x = 1

where x is cos (Beta)

x1= 0.54369
x2= -0.77184 + i * 1.11514
x3= -0.77184 - i * 1.11514

Unreal quantities for cosine angles is not possible, Kindly check the question
