What's some name of the books you guys have? Thank you in advance!
What are you looking for? the best Calculus book or books we use as references to do calculus problems.
One book I've always liked is the Schaums Mathematical Handbook of Formulas and Tables.
It has many integrals evaluated, identities for trig, vectors.... methods of solving differential equations and many other formulas useful for doing problems.
Separate names with a comma.
