    Orthogonal projection of 2 points onto a plane

    OK here we go. Calculate the orthogonal projection of points A(3,5,-1) and B(-4,2,6) onto the plane -2x+4y-z=3 r = a + tb <X,Y,Z> = <3,5,-1> + t<-2,4,-1> X = 3 - 2t Y = 5 + 4t Z = -1 -t aX +bY +cZ = d -2(3 - 2t) + 4(5 + 4t) - ((-1) - t) = 3 t ends up as -18/21 this time I...

    Orthogonal projection of 2 points onto a plane

    OK, I've found the co-ordinates of the projection of point A. But they seem odd to me. I have: x = 1/3 y = 10 and 1/3 z = -1/3 I solved t to 4/3, does that seem right?

    Orthogonal projection of 2 points onto a plane

    edit: This thread might need moved, sorry about that. Hi, I have ended up on this site a few times after searching various maths issues; it seems to have a good community so I am asking you good people for a little help understanding this. Tomorrow I have a semi-important maths exam, if I fail...
