Formula ffor a Scaler Equations of a plane

starn · 26-08-2009, 13:04

Hi Im doing some revison, and looking at the formula for a scaler equation of a line.

A(x-x0)+B(y-y0)+C(z-z0)=0

I realise this makes me sound like a complete dullard but I cant for the life of me rember what anything in the formula stands for. I know its pretty basic stuff. Ive checked my notes and Ive looked on line. But nothing. Can anyone help.

$(A, B, C) = A\vec{i} B\vec{j} C\vec{k}$ is a vector normal to the plane, $\text{[math]}$ is any point in the plane and x, y and z are your variables.
