If you are working with vectors or lines you will at some stage want to get the direction of a vector, or line. Or the direction from a point to another point. Math.atan(yComponent, xComponent) return the angle in radius within the range of -Math.PI to Math.PI (-180 to 180 deg) Direction of a vect...

If you have a vector in polar form (direction & distance) you will want to convert it to a cartesian vector with a x and y component. For referance the screen coordinate system has directions as 0 deg points from left to right, 90 (PI/2) point down the screen, and so on in a clock wise direction...

This bidirectional mapping requires the mappedBy attribute on the OneToMany association and the inversedBy attribute on the ManyToOne association. A bidirectional relationship has both an owning and inverse side. OneToMany relationships can use join tables, so you have to specify an owning side. Th...
