L 3_IMP — curve parametriche, Sjöberg / Harding / Bielby

Floppy IMG derived from archived files. Mount as FLP1 and boot using Minerva 1.98a1 ROM, 640 KiB emulator RAM and Toolkit II 2.32. Set t=0…2π and automatic X/Y ranges, then plotted the default x=sin(t), y=cos(t) curve in 2D. Checked closure and eight points of the unit circle, displayed with different horizontal and vertical screen scales. 3D plotting, printing and formula editing were not tested. Basic functional check in sQLux, not full validation or a physical-hardware test. Audio untested. ROMs are not included.
