Subject of a Formula
In this video we make the distinction between an expression, an equation, an identity and a formula. We also go through examples and explain how to make a variable the subject of a formula. This video corresponds with Chapter 2.4 in the Edexcel GCSE Mathematics textbook.

One of my favourite video about the laws of indices.
Nope. Lost you along the way.
Thanks a lot sir 👏👏👏
Bro just did the longer version
What's the shorter method?
oh my gosh ur so smart, thank you for teaching me how to do linear and non-linear sequence, I was so confused about it
Tack, mannen
How do you know its a quadratic sequence?
Beacuse in quadratic sequence the sequence dosnt go up in the same amount for example 4 , 9 , 16 , 25,36
WOW!!!!!! Just Awesome. Thanks.
very bad explaining
What to do when the second difference isnt equal like 2,5,11,23 have a difference of 3,6,12 and the second different is 3,6
But is that equal to 2a also?@junaidashraf7237
What about 0;8;8;16;24
Thanks 🙌
"the 2nd difference equals to 2a" divide the second difference by 2 basically
hi i have a math problem i use your method but it not correct. My sequence are 20, 18 , 15 , 11 ,6 i use your method make a position to term rules -0.5n^2 - n +21.5 and it not correct pls help me out and show me how it can be done
hi, it's actually -0.5n^2 - 0.5n + 21, so i think you might have just miscalculated when comparing -0.5n^2 to Un
thank you so much you helped me pass my gcse
This was relly helpfull, Thank you
How did you find (a ) on the second difference
This is really really clear 🙂
So helpful keep it up really helping me with revising 😁
Thank you so much! I can’t believe you have so few subscribers! You made this so much easier, before i did not have a clue! I have exams soon so I’m working on doing it as well as I can. You are wonderful!
