Question
If from the point P(f, g, h) perpendiculars PL, PM be drawn to yz and zx planes then the equation to the plane OLM is -
Options
A.
= 0
= 0B.
= 0
= 0C.
= 0
= 0D.
= 0
= 0Solution
From P(f, g, h) the foot of perpendicular on palne yz = (0, g, h),
similarly from P(f, g, h) perpendicular to z x = (f, 0, h) Equation of plans is
= 0 ⇒ 
similarly from P(f, g, h) perpendicular to z x = (f, 0, h) Equation of plans is
