I have found a magnitude to be the following:
4sin^(2) 2x + 4sin2xsinx + sin^(2)x
I now need to plot this using excel so I have rewritten it as:
4sin2xsinx + 2 -2cos(4x) + 1/2 - 1/2cos(2x)
4sin2xsinx +5/2 - 2cos(4x) -1/2cos(2x)
Using the fact:
sin^(2)x = 1/2 - 1/2cos(2x)
Is this correct?
4sin^(2) 2x + 4sin2xsinx + sin^(2)x
I now need to plot this using excel so I have rewritten it as:
4sin2xsinx + 2 -2cos(4x) + 1/2 - 1/2cos(2x)
4sin2xsinx +5/2 - 2cos(4x) -1/2cos(2x)
Using the fact:
sin^(2)x = 1/2 - 1/2cos(2x)
Is this correct?
