Functions and Mappings

Hi guys! In this excerpt I show you the difference between function and a mapping.

While all functions are mappings, not all mappings are functions.

Inequalities

Hi guys! I hope we are good?

In this short video I teach about inequality. We are used to equations in most mathematical questions. But there are scenarios where the LHS is not equal to the RHS. Then it becomes an inequality.

So head on to our YouTube Channel. It's the 9th video under our Algebra playlist

Integration by Partial fractions

Hi guys! This is an excerpt from the 16th video on our Calculus playlist

An understanding of partial fractions is needed here

Integration of Quotients ( expression and derivative relationship

Hi guys! Today I bring you an extract from our 15th video under our Calculus playlist.

There are some scenarios where you have questions written in this form: the expression and derivative together.

Differentiation of function of a function

Hi guys! What I have today is an excerpt from our tutorial on differentiation of function of a function. It's our 7th video on our Calculus playlist.

A function of a function is simply a composite function. It contains 2 or more functions embedded in one.

Differentiation of quotient of functions

Hi guys! Today I bring you an excerpt from our 6th tutorial under our calculus playlist

If you have been following the tutorials, you will notice that differentiation by first principle is a prerequisite for the derivation of this quotient formula

Sine rule and Cosine rule

Hi guys! Today I bring you an excerpt from our 5th video in the trigonometry playlist.

We learn here that for triangles that are not right-angled, we can use the sine rule or the cosine rule in solving them.

Enjoy the video.

Special Angles

Hi guys! Today I bring you an excerpt from our tutorial on special angles. It is the 3rd video in our Trigonometry playlist

One thing about special angles is that if you know how they were derived, so can easily memorize them.

Completing the square method

Hi guys! Today I bring you an excerpt from our 6th video in our Algebra playlist.

One thing to note is that you use completing the square method when (b^2) - 4ac is not a perfect square.

Equations

Hi guys! The video here is an excerpt from our introductory tutorial to Algebra. It's is the 1st video on our algebra playlist.

We learn a fundamental fact that you must always keep equations balanced because what we have on the LHS = RHS

Differentiation of product of functions

Hi guys! I hope we are doing well?

Today I bring you another excerpt from our video on differentiation of product of functions.

It is the 5th video under our calculus playlist. I hope you enjoy the video and don't forget to subscribe.
