EQUATION OF A PARABOLA FROM THE FOCUS AND DIRECTRIX
What is a parabola? How is it derived from conics?
Watch this presentation to find out.
Here, we learn how a parabola is derived when a plane cuts a cone. We learn that, for a parabola, distance of a point from the focus = distance of the point from the directrix. We solve problems based on this principle and also learn how to calculate equation of the axis and the coordinates of the vertex.
This is useful for grade 11 maths students. This channel has videos for grades 11, 12, engineering maths, nata maths and the GRE QUANT section.

INTRODUCTION TO FUNCTIONS
What are sets, relations and functions?
This presentation starts with the Cartesian product of 2 sets and how a relation is defined from it. It also goes on to show how this leads to a function . We cover the different types of functions and problems based on them. Types of functions explained are one-one, onto, many to one and into functions.We discuss 3 important functions, namely, the modulus function, signup function and the greatest integer function.
