Projection u onto v formula
WebThe vector projection of u onto v is the vector which has magnitude given by the scalar projection comp u ( v) and points in in the direction of v, which is given by the unit vector v v associated to v. Hence we have proj v ( u) = comp v ( u) v v = ( u ⋅ v v 2) v. I hope that this helps! Share Cite Follow edited Aug 27, 2012 at 3:21 WebThe vector parallel to v, with magnitude comp vu, in the direction of v is called the projection of u onto v and is denoted proj vu. So, comp v u = jjproj v ujj Note proj v u is a vector and …
