Unformatted text preview: ugh the points Q, R, and S , then the distance, d, from P to that plane is given by the formula Express the distance d from P to ℓ in terms of the vectors − − → a = QR , |a × b| . | a| keywords: distance, distance from line, cross product, vectors D b |a × b| . | a| ℓ R Q |a × b| correct | a| |b| sin θ = Let ℓ be the line passing through points Q, R and P a point not on ℓ as shown in 7 d= | a · ( b × c) | |a × b| where − − → a = QR , − → b = QS , − − → c = QP . Use this formula to determine the distance from P (2 , 4, −3) to the plane thr...
