Thanks Bill! I believe this is the most efficient way given the known
parameters. --- In , Bill Driscoll <bill-driscoll@r...> wrote:

Here is one way:
h=3; k=5; r=7; N%6;
t=(0:N)*2*pi/N;
plot( r*cos(t)+h, r*sin(t)+k);
axis('square') Franklin Rosario wrote:

hi!
i am not very sure if there is a inbuilt function to draw a circle. so
the best thing to do is to consider some number of points and use the
equation of the circle to get the points.
then u can use the plot method to plot all those points.
have fun
regards
venu

i need to plot 2 lines (e.g. Ax+By+C), 2 circles (e.g.(x-h)^2 + (y-k)
^2 = r^2), and 3 points (e.g. (x1,y1), (x2,y2) & (x3,y3)) all in one
plot, for instructional purposes.
how do i plot a circle centered at (h,k) with radius r?
thanks in advance
