Question 921647
actually i want to calculate all the points lying on a circle so that i can plot a graph, when xcenter=5 and ycenter=5 and radius= 12 , can anyone help me in calculating each point lying on the circle.
-------------------
{{{(x-5)^2 + (y-5)^2 = 12^2}}} is the circle
You can solve for y
{{{(y-5)^2 = 144 - (x-5)^2}}}
{{{(y-5) = sqrt(144 - (x-5)^2)}}}
{{{y = 5 + sqrt(144 - (x-5)^2)}}}
-----
Use the +sqrt for 1/2, then the -sqrt for the other half.
