A-Level Maths: H5-05 Further Integration: Reversing the Chain Rule with Trigonometry

[katepassman]

This is such a better explanation than the textbook which I swear is trying to make it as complicated as possible

My man, there’s more letters than numbers 😂😭😭

sir what happened to the cosx when integrating?

Hi Jack, a very basic question at this later stage in your course! (following along on your website which is incredible btw). Why does (sinx)^2 expand to sin^2x and not sinx^2. What would be a situation that expanded to sinx^2 instead

Why do you not do one over the outside in the first example 1/3 as you did in the second example with the 1/5?

How come you cant use the product rule to differentiate. its kind of confusing to figure out if product or chain rule should be used.

sir would this still work if it was cos(2x)(sin(x))^4 or no? if not what method would you use???

[vijval]

why can you not integrate sin^3x by reversing the chain rule?

[karotic]

i thought the differentiation of sinx^5 was 5x^4 cosx^5

[katana]

Can you make a video doing this with trigonometric identities?
