sin vs sin1, and other cognates (help !)

Postby guyman » Wed Mar 31, 2021 10:31 pm

hey hey

I'm in the alpha toolbox and I see stream math functions for sin1 cos1 and tan1, and I had some modules for these in the old version.. but I need sin cos and tan...

I know these are interchangeable, and saw a post about sin1 vs sin before... but things aren't adding up when I implement.. does anyone have a schematic that can show how to prepare an input for the sin1,cos1,tan1 ... to get the solutions for sin, cos, and tan.. or prims that just give the sinx cosx tanx.... each one.. STREAM/DOUBLE STREAM ONLY.. no green.

and any other handy stream functions would be killer right now... I'll dig thru what I got and share when I get home.....

Flowstone's sin1 function is just the ordinary sine function with its argument scaled by 2*pi:

sin1(x) = sin(2*pi*x)

While a full cycle for the sine function is 2*pi (in radians), a full cycle for sin1 is 1.

Note that Flowstone's green implementation Sin is the ordinary sine function of an unscaled argument in radians, so bear that in mind when you precompute stuff in green.

I have noticed that the flowstoneguru site is down for good, so I post my collectiion of stream math functions below.
