Course Overview of 3D geometry, followed by a brief introduction on 3D and what you can expect from this course.

Course Overview

This lesson talks about the 3D space. Foundation lesson on 3D. We learn about octants, planes, and basic formulas such as distance formula and section formula and examples.

The 3D Space

This lesson talks about vector representation of a point in 3D, direction cosines and direction ratios, important properties and relation of drs and dcs, and also about finding angle between 2 lines.

Direction Ratios and Direction Cosines

Some of the problems involving direction cosines have been discussed here. Starting from the basics to some questions relevant to competitive exams.

Examples on Direction Cosines

We study about lines, representation of lines in their most common forms, coplanarity of points, and projection of vectors.
