A Conceptual Introduction to Several Variable Calculus

A conceptual introduction to differential calculus of several variables. Weans away the students from mindless computations and introduces them to a single (geometric) trick which is employed in the proofs of the most of the results. Also, brings out the geometric meaning of the partial derivatives.

Nested Interval Theorem and Its Applications

Proves the nested interval theorem and gives its applications such as intermediate value theorem, Heine-Borel theorem, Bolzano-Weierstrass theorem, extreme value theorem. Also gives two unusual applications: density of rationals and Volterra's proof of nonexistence of a function which is continuous at rationals and discontinuous at irrationals.
