Dear All

For the line crossing from points P0(x0,y0,z0) and P1(x1,y1,z1) and in the direction of vector P0P1 we know that :

P0P1 (x1-x0,y1-y0,z1-z0)

So the line equation will be :

(x-x0)/(x1-x0)=(y-y0)/(y1-y0)=(z-z0)/(z1-z0)

So how we can obtain the coordinates of the middle point M(x,y,z) on the P0P1 line with equal distance from P0 and P1?

(Can you please let me know how can I write mathematics formula here? For example, writing them in Microsoft Word 2007 and then copy-paste here?)
