Usage

Linear Euation

final line = MathHelper.getLineEquation(offset1, offset2);

Circle Equation

offset is center point, radius is radius of the circle.

final circle = MathHelper.getCircleEquation(offset, radius);

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);
