Hi,
I was trying to plot circle equations and found a strange bug:
When plotting following equation:
0.66^2 = (x-1)^2 + (y-1)^2
the circle is plotted correctly as expected.
But when taking the square root first on both sides:
0.66 = sqrt((x-1)^2 + (y-1)^2)
the circle printed has nearly double the radius as expected. Also I tried to verify if the radius is really "double" the expected one by plotting a vertical line in the same plot:
0.66 = sqrt((x-1)^2 + (y-1)^2), x = -1.32
This however plots the correct circle.
When I'm missing something here, I apologize.
Best regards!
