e) Calculate the frequency and number of output pulses in each section
Destination: Draw 10 sections of arcs clockwise until they reach (50,000, 50,000) (see figure 10)
Rx = target value in X; Ry = target value in Y; N = number of sections; π = 3.1416

Step 1: Calculate the position for each section
x
1
= Rx – Rx × sin [(N-1) × π ÷ (2 × N)]
x
2
= Rx – Rx × sin [(N-2) × π ÷ (2 × N)] …. See table 3
y
1
= Ry × sin [1 × π ÷ (2 × N)]
y
2
= Ry × sin [2 × π ÷ (2 × N)]…. See table 4
