If i had a maths teacher like you at the beginning i would've never hated maths

best match a level teacher i have ever seen, the way you say is really to understand for me

[xwjfdnl]

bro I am not even gonna lie here, my maths teacher took 2 lessons (1 lesson = 1.5 hour) to teach this mapping and functions and i didn't understand anything and i even asked her like 200 questions just so I could understand this but she was explaning it in such a complex way that it just couldn't get in my head. And then there is this guy who taught me this in less than 20 mins and I am feeling so confident now.

Wallah i love your teaching so much, you have made me interested in maths again after my school killed my interest in it. Thank you so much. When I watch you, all my procrastination floats away. Thank you for your amazing videos

Nice video, sir! Just one mistake at 19:44, it can't be -4 as the function x^2+3 is only defined for greater than or equal to 1

Thank you so much, i wish i could get a teacher like you

Gonna compliment my wife how this guy compliments his graphs 😂

Hello there, do you recommend doing the E/P and P questions from Mixed Exercises only or from the whole book? Thank you for the content, it genuinely helps a lot!

Quick Question:
Is it worth doing the whole exercise for each subtopice or just the Mixed Exercise?

[protekkers-football]

Hi sir at 16:20, would that graph not be considered as a function because when you input the value of x as 0 you don't get an output.( I thought functions are mappings where one input has exactly one output.)
