POINTAT (degrees,radius,cx,cy)

• $degrees$ is any degree value.
• $radius$ is the radius value of the circle.

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 $COS(\theta )$=${\frac {x}{r}}$.
• Using this function we can find the coordinates of the point on the circle is $x=rCos(\theta )$ and $y=rSin(\theta )$.
• On a unit circle, a circle with radius 1,$x=Cos(\theta )$ and $y=Sin(\theta )$.
