Hi,
Attached I have a picture of my problem. I know that every circle can be said that is surrounded by a square, but I need to know certain point on a circle. How is that possible pls?
1. The equation of your circle is:
$\displaystyle (x-250)^2+(y-250)^2=150^2$
To calculate the coordinates of a ceratin point you must know either the x-value or the y-value of the point.
2. If you know the angle $\displaystyle \alpha$ between the given radius and the point in question then you can calculate the coordinates of the point P:
$\displaystyle x_P=250+150\cdot \cos(\alpha)$
$\displaystyle y_P=250+150\cdot \sin(\alpha)$
