Dear people,

I need to calculate the projection of a 3D vector, but I don't know how. Could you please help me?

There are two 3D vectors:AandB.

AandBare both on planeP.

Lis a line onP, through the origin, and perpendicular toA.

How do I calculate the vectorCwhich is the projection ofBonL?

Thank you for your time!

Cornelis
