Learning quant quickly? My review of FREE **Multivariable Calculus ****By George Cain & James Herod**

So In finished reading this Multivariate Calculus book

http://quantlabs.net/labs/quant-books/doc_details/800-multivariable-calculus?tmpl=component

It seems this book is really designed for more advanced calculus users as there are some assumptions of knowledge. Still it is a very good resource if you trying to learn quant, but when your head is spinning after Paul WIlmott or John Hull, this would be a good resource to understand some of the calculus terminology thrown around. If you still don’t get it (like me), you may want to further investigate on good YouTube channels (like Khan Academy) some of the key terms listed below from the book’s table of contents:

Of course some of the topics do apply to quant but others do not so you can omit what you don’t want to read.

Now I got to read that 1000 page linear algebra book now I would probably start with this before even touching the above calculus book. There is some mention of algebra as well s that confusing math manipulation I can never get.
