I noticed that the graphs of sin(x) and sin(x) ^ 2 are very similar. So I offset sin(x) ^ 2 to exactly match sin(x):
[tex]sin(x) = 2 sin^{2}\left(\frac{x}{2} +\frac{\pi}{4}\right) - 1[/tex]
Is this right, or is it an illusion? I haven't been able to find any identity that this is based on.
If it is right, then:
[tex]sin^{2}(x) = \frac{sin(2x - \frac{\pi}{2}) + 1}{2}[/tex]
Thanks,
