The way you explain is so calm and easy to follow, dont know where I’d be without this man 🙏

brilliant video, i do ocr mei b and in our paper 3, one of the topics is "Binomial expansion; area under a curve", any idea what that would be?

[darcey]

In the OCR paper 1, we dealt with a similar question! Except it asked you to show that *insert implicit equation* has no points on the curve that makes it’s tangent parallel to the line y=x

its just coincidence that both co-ordinates are just swapped around right ? so you can't just find one set of coordinates and switch ?

i dont understand why dy/dx is infinite when dx/dy is 0? Could you plz explain?

[nynthes]

You can also just flip dy/dx to get dx/dy can;t you?
