Fit a line into a circle based on centrepoint and angle in degrees

[henk_kempen]

Hi everyone,

I want to fit a line based on two values I got , the centre (x,y) and the angle in degrees from the top of the circle, is this possible? (see the attached picture for more clarification)

Sure, just draw a line from (x,y) to (x+radius*cos(angle),y+radius*sin(angle))

Angle needs to be in radians (so angle=2*pi*angle in degrees)

In fact you probably need to faff about a bit to get the angle as you defined it, so in the top equation I think it would actually be (90-angle) in place of angle. Try it and see what it does.

Thanks, I will give it a try!

btw, you said:

... to faff about a bit...

What does that mean (I'm from the netherlands and don't speak english very good:))

doesn't matter, it worked perfectly!! many thanks!

Angle needs to be in radians ( that didn't work with your way, i did it by divide the degrees with 180 and multiply it with pi)

There are also "degree to radians" and radians to degrees" functions on the pallette somewhere. I usually locate them with the quickdrop (ctrl+space), they're just already-filled expression nodes, but they save you some time...

EDIT: Programming -> Numeric -> Scaling

I don't have it in Labview, probably It's a function in newer labview (I use 2010 fall)
