The point (a, b, 0) lie on:
In 3D Cartesian coordinates, any point is represented as (x,y,z).
Since the z-coordinate is zero, the point lies on the XY-plane, which is defined as the set of all points where:
Z = 0
This plane includes all points that extend along the x and y axes but do not move in the z-direction.
The point (a, b, 0) lie on:
Find the angle between the planes and .
If a line makes an angle of 60°, 135°, 120° with the positive x, y, z-axis, respectively, then find the direction cosines.
The equation of the plane that passes through (1, -1 2) and has direction ratios (1, 2, 3) is:
Find the distance between two points (2, 6, 5) and (2, 3, 9).
Which of the following represents direction cosines of the line?
Find mid point of (4, 3, 6) and (6, 5, 12).
If P (2, 3, 4), Q (5, 8, 7) and R (-1, -2, 1) are collinear, then R divides PQ in the ratio:
