Well, good for you!

MathWonk, he is referring to "Calculus and Analytic Geometry" by Thomas and Finney which is really the classic text by George B. Thomas as revised by Ross L. Finney.
When I took Calculus I, Thomas was my instructor. I remember that I had to pay $24 for the text- and it hurt!

Though I can't help but wonder why hairlosstreat wants to tell us he has that book.
 


well after googling them both, it seems finney died in 2000 and thomas died in 2006, which explains to me the significant decline in quality of the "thomas calculus" books over the last 15 years. i still prefer the one I had in 1970, written just by thomas. it must have been a privilege to be taught by him Halls, but you apparently paid dearly for it!

That was apparently much later than my freshman year, when i bought courant for my college calculus course, taught by john tate, for $6.50. tate is apparently still alive and only recently retired from ut austin after a teaching career spanning over 50 years at harvard and ut.
 
I am still wondering why this thread was opened. I rather suspect that "hairlosstreat" was trying to sell the book. Oh, well, that still is better than being offered a treatment for hair loss!

There are at least two editions of Calculus by "Finney - Thomas," (authors' names are reversed) which I don't think counts among the 12 editions of Thomas' Calculus. https://www.amazon.com/dp/0201549778/?tag=pfamazon01-20 is Amazon's link to the 2nd edition, from 1994.

There is also an edition by Finney-Demana-Waits-Kennedy, which I believe is based on the Finney-Thomas text above. There's a regular version (some titled Calculus: A Complete Course), and there's a single-variable version (Calculus: Graphical, Numerical, Algebraic), which is what a number of high schools use for their AP Calculus courses.

my engineering college prefers this Finney book. I don't think it is rigorous like Apostol. My instructor says that we have to do epsilon-delta proofs from this book. Even Apostol has some problems pertaining to it. I think I can use Apostol itself. Please suggest me which book to use..
