Use vector equations for projections onto planes - identity proof
Point P(2,4,1) is projected onto the plane \(2x+2y+1z=8\) along the normal \((2,2,1)\). Enter the projection multiplier \(\lambda\) along the normal.
Worked practice: result and interpretation
Calculate the requested result first, then choose the interpretation that follows from it.
