at 7:58, isn't it supposed to be -1 / 4(x^2 -3)^2

Thanks for this ! Also, at 9:10 you took Y=e^x^3 .shouldn't we add 1 to the power when doing rough integration so it would be Y=e^x^4 ? or does it not apply to 'e^x"

For question 2b (8:24) I think you've made a mistake in differentiating cos2x. Should it not be -2sin2x?

hello sir, at 7:58, isnt the rough integration supposed to be (x^2-3)^-2/-2? if im wrong, please correct my steps.

At 4:05 when you're doing rough integration, why did you add 1 to the power?

Should we think about the inverse chain rule for all sorts of problems to see if I can use it or is there an easier method to identify when I should use the reverse chain rule?

Thank you so much for these really helpful videos! Your explanations are quite simple and very easy to understand and i find it much easier to solve questions! If possible, can you make videos solving past paper questions in the future?
