how can i plot a circle intersect with a line

i want to write a program that can help to plot a circle intersect with a line

[Geoff Hayes]

amro - please elaborate on the problem that you are trying to solve. What are your inputs for the line? What are your inputs for the circle?

[amro faira]

xc=6

xc =

     6

yc=5

yc =

     5

r=2

r =

     2

theta=90

theta =

    90
and for the line 
xo=6

xo =

     6

yo=7

yo =

     7

xf=4

xf =

     4

yf=8

yf =

     8

i already have the parametric of circle and line i just need a formula to insert the input to plot the intersect or what should i do

for t=0:0.001:1 x(i,1)=xo+(xf-xo)*t; y(i,1)=yo+(yf-xo)*t; i=i+1; ---------------------------------------- for theta = 0:pi/100:2*pi i = i+1; x(i) =xc+r*cos(theta);

    y(i) = yc+r*sin(theta);

circle intersect

[Roger Stafford]

@Stalin - This function, 'circcirc', which you give as an answer, is for finding the intersections between two circles, not between a circle and a straight line! I think you meant to reference this function:
