Looking for other FFT window types


I’m looking for new window types for FFT processings or to be used as amplitude envelopes.
I already use Hann, Hamming and Cosine windows.
For the Blackman, I have:
w(n) = 0.42 – 0.8 cos(2*Pi*n/N) + 0.08cos(4*Pi*n/N)

I’d like the sine and some others.
Defined as Max expressions would be very cool.

Thanks in advance!

Sorry for the typo.
Please read:
w(n) = 0.42 – 0.5 cos(2*Pi*n/N) + 0.08 cos(4*Pi*n/N)

And not:
w(n) = 0.42 – 0.8 cos(2*Pi*n/N) + 0.08 cos(4*Pi*n/N)

Any help?
