Homework Statement in the parallelogram ABCD, DC is extended to E so that DE:EC= 3:2. The line AE meets BC at F. Determine the ratios in which F divides BC and F divides AEThe Attempt at a Solution so i figured i could use the division-point theorem OP=[b/(a+b)]*OA +[a/(a+b)]OB but i don't...

Homework Statement Give parametric questions for the plane : 2x-3y+z-6=0 The Attempt at a Solution i know that the normal is (2,-3,1) how do i find the direction vector of the plane?

oh i finally figured it out.. i just need to do the cross product of the two dirction vectors of the two line..

Homework Statement find the parametric equations of the line through A(-3,2,5) and is perpendicular to both line 1 and line 1 where line 1: (x-4)/3=y-2=(z-3)/-2 line 2: (x,y,z)=(-1,1,5)+k(-1-2,3) 2. The attempt at a solution i think i need to find the normal for the line 1 and...
