How to spin (or rotate) a shape

[rempesm]

@Z0NK0UT

cos(α+β)=cosαcosβ−sinαsinβ
sin(α+β)=sinαcosβ+cosαsinβ

sinα and cosα are the H and V ramp inputs.
sinβ and cosβ are the internally generated Sine/Cosine quadrature waveforms.
sin(α+β) and cos(α+β) are the HV outs

I’ll draw up a diagram in a minute.
