about

nx_viz_trig.nx -- the TRIG layer of the sovereign Nishi viz library (hardware-rung-up: pure INTEGER sin/cos, no FPU, no lookup table). Bhaskara I's sine approximation: sin(d deg) ~= 4d(180-d) / (40500 - d(180-d)), accurate to ~0.16% -- exact at 0/30/90/150/180. Output scaled by 10000 (sin(90)=10000). Range-reduced to [0,360). Unlocks arc/pie shapes + radial/force layouts. license_tier: ORIGINAL
