Discrete Mathematics 1: Introduction and Bubble Sort

On a starting note, this is covering the OCR D1 Math course. I know it's not Chemistry but I wanted to do it anyway.

By the end of the video you should know what an algorithm is and be able to apply the Bubble Sort.

THANK YOU VERY MUCH SIR, FOR TAKING YOUR PRECIOUS TIME TO PRESENT THIS TUTORIAL. PLEASE SIR, I AM NEW TO THIS KIND OF MATHS, HERE ARE SOME QUESTIONS, I NEED YOUR HELP ON THIS ONE...



1. (a) The universal set is {1, 2, . . . 10}. Let A = {1, 2, 3, 4, 6, 7}, B = {2, 3, 4, 5, 8} and
C = {1, 3, 5, 6, 8, 9}. Find the elements of the following sets:
(i) A∆B
(ii) (A ∩ B)
′\C

(b) Given the relation R such that R = {(m, n) ∈ R|m, n ∈ A, m2 − n ≥ 4} when A
is the set {0, 1, 2, 3, 4},
(i) express the relation R as a set of ordered pairs.
(ii) draw an arrow diagram to represent this relation.
(iii) investigate whether the relation is symmetric, transitive and/or reflexive.

(c) Determine if the following functions are one-to-one and/or onto and use these to
determine whether the function is a bijection. Assume both functions are such
where f : R → R.
(i) f(x) = 6x − 9
(ii) f(x) = x
2 − 2x + 1

Sometimes you can only understand the complex concepts, when you have understood the simple concepts. Fantastic introduction to discrete mathematics that should help me as I enter more challenging areas.

For once I understand math, you are a great teacher.

Hi, your teaching technique is good and helpful. Can you do some more videos about discrete mathematics? It'll be extremely helpful if you can provide videos about Composite Relations

PLEASE FINISH THESE VIDEOS!!!! I WILL BE WATCHING!!!
