Imagine you are an ant walking on a circle. You start your journey from the blue point. Your progress is given in percentages - 100% being a full round trip. In the figure, you've made a progress of 40% and reached the orange spot.
If you're told the percent-progress of your journey (such as 40%), how will you calculate your current coordinates?
You know these:
- Radius = 50
- Starting coordinates = (50, 0)
- Y axis is inverted - positive values are on the bottom (as in figure)
- Circle border has zero thickness
