How to calculate this ?

maybe he wants the formula for the whole square, not just x3,y3 point

 

He doesnt know what he wants lol

 

You wrote :

x3=x1+d, y3=y1+d

So why doesnt ???

x2 = x1+d
y2 = y1+d

 

its not the same becuase you are dealing with a circle not a square. In the case you named, D would not equal the radius but some distance shorter than the radius. The only time what you wrote is true is when you are dealing with 0 degree, 90,180,270

 

Thanks all this worked


x3=x1+d, y3=y1+d

 

Lets make this easier. Assume that X1, Y1 is (0,0) and D is equal to 4 (whatever units you want doesnt matter).

the formula is 4^2=X^2 + Y^2

In this case you can determine any X2 or Y2

 

maybe because you are mixing up coordinates and distance

 

Isnt this the story of Jack Hershey? taking the most easy shit and making it so complex that not even he understands it.

 

Meaning: Old, especially of horses or people. So I guess you must be a horse ...

 

LOL!!!
