Question

OABCDE is  a right triangular prism with OA = 2units , OD= 2units and AB = 4 units. The unit vectors i,j and k are parallel to OA,OD and OC respectively.
a) Find the unit vector parallel to DB.

oobleck · Answer

are the two triangular bases OAB and CDE? and the three lengths OC, AD and BE?

Dani · Answer

the bases are OAB and OCB. and the lengths are OD , AD and BE

oobleck · Answer

Sorry. In a prism, the bases are parallel and thus do not intersect. Points O and B cannot possibly be in both bases.
