The equation of x-axis in space are
As we learnt in the concept
Co-ordinate axes -
There are infinite points in plane we want to identify them by using three mutually perpendicular lines known as co-ordinate axes
- wherein
Co-ordinate of a point -
Consider a point P(a,b,c) in space and drop a perpendicular from it on XY plane the algebraic length of this perpendicular is called z cordinate. Now from this point draw perpendiculars to X and Y axes, the algebraic length of these perpendiculars is known as x and y co-ordinate respectively.
- wherein
y=0, Z=0
