I want to re-study differential and integral calculus of one and of several variables and be able to solve all kinds of low to high level problems related to them. Iit has been 3-4 years I solved integral problems in high school and now I want to prepare for GRE math subject test whose 50% syllabus is
"Material learned in the usual sequence of elementary calculus courses — differential and integral calculus of one and of several variables — including calculus-based applications and connections with coordinate geometry, trigonometry, differential equations and other branches of mathematics."
After googling for a while, I thought about going with these two classical books
I could not find any reviews of this book. Is this a right choice, as I believe if I can make my concepts clear then any problem is easy. Or should I buy another modern texts, if so, please recommend.
