This video applies the chain rule discussed in the other video, to higher order derivatives.

Don't skip the product rule step, it's the only problem in the example.

How do you get the part that is in red?? ate 3:12???

For guys who don't understand the product rule, you use the method of A'B + B'A

Thank you, my professor's example left my brian dusty

I was about to drop my class. I'm glad I didn't cause this isn't too bad if well explained.

Thinking of the first chain rule df/ds as d/ds (f) and substituting df/dx and then df/dy helps

[Aqeel]

That's fucken difficult equations 💔😭
