Let A = aP + bP2 , where a and b are constants.
Sub. P = 24 , A = 36 ,
24a + 576b = 36
2a + 48b = 3 ………… (1)
Sub. P = 18 , A = 9 ,
18a + 324b = 9
2a + 36b = 1 ………… (...

The easiest way of approaching this question is to use De Moivre's formula: e^(inx) = cos(nx) + isin(nx) from which it is simple to show that cos(nx) = (e^(inx) + e^(-inx)) / 2 and sin(nx) = (e^(inx))- e^...
