I am trying to graph a section of a circle into an array. I have been trying to wrap my head around [sin] and [cos] but none of my configurations get results. If you had a circle with radius 100 with a center at (0, 0) I'm trying to get the upper right quadrant (positive x and positive y). The start point being (100,0) and the end point being (0,100).<br>
<br>
Any ideas on moving forward?<br>

use angles between 0 and pi/2 = 1.5708<br>
<br>
putting those into [cos] and [sin] will give you values for a circle of radius 1 at (0,0). For different radiuses you apply [*] after that.<br>
<br>
quadrants and clockwiseness depend on which axis uses [cos], which axis uses [sin], and which direction of each axis is positive. There are several standards for those things.<br>
