PARTIAL DERIVATIVES
Functions of Several Variables
Definition
A function f of two variables is a rule that assigns to each ordered pair of
real numbers ( x, y) in a set D a unit real number denoted by f ( x, y). The set D is the
domain of f is the set of

Calculus of Variation
The calculus of variation is a powerful technique for the solution of problems in dynamics of
rigid bodies, optimization of orbits and vibration problems. The subject primarily concerns
with finding maximum or minimum value of a defi

Eigen Value Problems
Gerschgorins Theorem:
The largest eigenvalue in modulus of a square matrix A cannot exceed the largest sum of
the moduli of the elements along any row or any column.
Example: Find the interval which contains the eigenval
