Assignments and Methods of Evaluating Student Progress:

1. Typical Assignments a. Let f be a function of two variables that has continuous partial derivatives and consider the points A(1, 3), B(3, 3), C(1, 7), and D(6, 15). The directional derivative of f at A in the direction of the vector AB is 3 and the directional derivative at A in the direction of AC is 26. Find the directional derivative of f at A in the direction of the vector AD. b. Two legs of a right triangle are measured as 5 m and 12 m with a possible error in measurement of at most 0.2 cm in each. Use differentials to estimate the maximum error in the calculated value of (a) the area of the triangle and (b) the length of the hypotenuse.
