this video will teach you how to form the new quadratic equation when the new roots of quadratic equation are given.
This video will guide you through the step by step process.
Hope you find it helpful to you =)

this question is not in SPM or IGCSE syllabus. I posted here just to help a student to score well in his exam. At the same time, I hope this extra knowledge ...

I think both of these questions apply to SPM and IGCSE Add Math students. However, both of these question is getting from CIE IGCSE syllabus.
Permutation - 4304 - s15 - 12 -Q5
Combination - not sure is from Text book or past year paper.

In this video, I will cover almost everything you need to know about domain and range for function and "inverse function". Hope through this video can help you score easily in your exam. Hope you really like the video. Please share it to your friends =)

this video involve double angle of trigonometry function.
KBAT mean "higher thinking skill" question.
In this video you will learn how find sinA, cosA, tanA, from sin2A.

this video will teach you how to differentiate and integrate exponential function, using a lot of different example to make you understand better about how to do it. You will need to practices more to sharpen your skill.
