The document discusses partial derivatives and differential calculus for functions of two variables. It provides definitions and formulas for calculating the partial derivative of a function z with respect to t, when x and y are functions of t. It also discusses using the chain rule to calculate the derivative of a composite function z(t). Examples are provided to demonstrate how to apply the formulas to calculate partial derivatives.

1. The document defines functions and their domains, ranges, and continuity. It provides examples of limits of multivariable functions and discusses properties of functions like continuity at a point.
2. It examines limits of multivariable functions as variables approach certain values. Examples are worked out, finding limits as variables approach 0 or other numbers.
3. Discontinuous points of functions are defined as points where the limit of a function as variables approach values is not equal to the function value at that point. Examples identify discontinuous points of various functions.
1. The document discusses methods for finding integrals of rational functions.
2. It states that the integrals of many rational functions can be found by decomposing them into partial fractions.
3. An example is provided to demonstrate decomposing a rational function into partial fractions.
The document provides information about Riemann sums and Riemann integrals. It states that if f(x) is a non-negative function on the interval [a,b], then the graph of y=f(x) can be approximated by dividing the interval into n subintervals and taking the left or right Riemann sum of the resulting rectangles. The Riemann integral from a to b of f(x) is defined as the limit of these Riemann sums as n approaches infinity. Newton and Leibniz developed the fundamental theorem of calculus that relates integrals to derivatives.
