|Class 12 Maths Three Dimensional Geometry||Introduction|
We will learn about the 3-D geometryand also about the 3-D coordinate system.
How to make use of vector algebra in 3-D geometry.
We will discuss about the direction cosines and direction ratios of a line joining two points and also about the equations of plane and lines in space under different conditions.
In case of 3-D the three coordinateplanes divide the space into eight parts known as octants.
Some examples of where 3-D geometry is being used:
