POINTAT (degrees,radius,cx,cy)

Description

This function used to find the points on the circle using radius of the circle and degree value.
In $POINTAT(degrees,radius,cx,cy)$ , $degrees$ is any degree value.
$Radius$ is the radius of the circle.
Consider a circle centered at the origin with radius r, and marking the point on the circle indicated by some angle θ.
For the point (x, y) on a circle of radius r at an angle of $\theta$ ,the the function $SIN(\theta )$ = ${\frac {y}{r}}$ and $COS(\theta )$ = ${\frac {x}{r}}.*Usingthisfunctionwecanfindthecoordinatesofthepointonthecircleis<math>x=rCos(\theta )$ and Failed to parse (Conversion error.
