Function x = Asin^(2)omegat + Bcos^(2)omegat + C sinomegat represents SHM

Answer»

for any value of `A,B` and `C` (EXCEPT `C = 0`)
If `A = -B,C = 2B`, amplitude `= |Bsqrt(2)|`
If `A = B : C = 0`
If `A = 6 : C = 2B`, amplitude `= |B|`

Solution :`x = A((1 - cos2omegat))/(2) + B ((1 + cos2omegat))/(2) + (C)/(2) sin 2omegat`
Choose different combination of `A, B` & `C` to get LINEAR combination of `sin` & `COS` functions.
