I always love the way you teach... feels like I'm in a classroom, too.

I have 1 question.
Normally r>0, when I exponential form, i mean at Alevel, it's specified in the question.so we need to give r as positive.
So is it acceptable to write r=-2, in the answer you gave for exponential form?

I love these videos and we don’t even do this level of maths in school until uni

Feels like I’m in the classroom, it’s a lot of fun!

You know, you could have said C=R^2 and called it a day.
