Circle Equation #
offset is center point, radius is radius of the circle.
final circle = MathHelper.getCircleEquation(offset, radius);
copied to clipboard
Distance #
/// Calculate the distacne between two point
final distance = MathHelper.getDistanceBetweenTwoPoint(offset1, offset2);
/// Find the point of intersection between the given point and the given line perpendicular to it
final distance = MathHelper.getPointVerticalToLine(line, offset);

Intersections #
/// Intersection between Line and Circle
final points = MathHelper.getIntersectionBetweenCircleAndLine(line, circle);
/// Get the perpendicular equation from p1 and given linear equation
final line = MathHelper.getIntersection(line, offset);
/// Get the intersection point of two linear equation, if there is no intersection point, will return null
final point = MathHelper.getTwoLineIntersection(line, line2);
/// Find the point of intersection between the given point and the given line perpendicular to it
final point = MathHelper.getPointVerticalToLine(line, offset);
