Homework Statement
Using the Ax+By+Cz+D= 0 equation for planes, where D = -(Axo, Byo, Czo)
Find the locus given by the equation if A and B = 0
note: I'm not 100% sure if locus is the right word, english isn't my primary language.
Homework Equations
Given above.
The Attempt at a Solution
Well, if A and B = 0, the equations can be written as Cz+D = 0.
Which means z = -D/C = (0x + 0y Czo)/C = zo
Since we're in a 3 dimensions space, the way I see it both x and y are unrestricted and can take any values. Does that mean the locus defines a plane parallel to the X and Y axis, at a Z value of Zo?
