Drawing Tangent to the Circle using a External Point

Highlighted

 

From the Following Image, The Point P(x,y), Radius(R), Center (0,0) are known values. My aim is to Find the two possible tangents which intersect the Circle at T1(x1,y1) and T2(x2,y2).

 

In Labview, I am not using Picture plot functions to do this. I use some mathematical formula and I showing the Output in XY Graph. Some Plotting is based on Co-ordinate points (i.e.., x and y).

 

I want to know the point ( T1 and T2 ) which intersect the circle as a Tangent line which is passing through the Common point P(x,y). How I can do in Labview..?

Thanks in Advance...

Well, you say you have the formula. What prevents you from just implementing it in LabVIEW? Smiley Wink

What have you tried so far and what problems did you encounter? Is this a homework question?

Thanks for Reply.

 

This is not a Homework Question . Its a little part of my project which is Designing CAM Profile.. So far I didn't get any problem. Now I want to find the value that two co-ordinate points by using those given inputs. That's it...

So that's a math question, not a LabVIEW question. Start reading here. See how far you get... Smiley Very Happy
