Right, and in this case, SIN is incremented in very tiny steps t = 0.25 A = 10.0098 t = 0.5 a = 10.0392 t = 0.75 a = 10.0883 t = 1.0 a = 10.1570 t = 1.25 a = 10.2454 t = 1.50 a = 10.3533 t = 1.75 a = 10.4809 t = 2.00 a = 10.6281 t = 3.00 a = 11.4130 t = 5.00 a = 13.9220 Im just not sure how to imple...
