```Math 125 Test 2 Review Suggestions Fall 2005
For a given linear programming problem, determine the feasible space and its corners and determine
the optimum solution.
Be able to set up a linear programming story problem.
Know how to work with the postnet codes.
Know how to work with ISBN.
Know how to work with Soundex system.
Know how to work with other check digits if given the proper information.
Determine a binary linear code of given message length when given the parity check sums.
Find the distance between code words.
Find the weight of a code system and use it to determine error detecting and correcting
capabilities.
Use the nearest neighbor method of decoding.
Know how to add binary linear code and determine which customer has not paid bill for premium
channel. This item will be counted as a bonus question if given.
Be able to encode and decode with variable length code and explain why use of variable length
Calculus
Find a derivative (that is, find f’(x)) and know that the values of the derivative evaluated at a point gives
the slope of the curve at a point on the curve, and in the case of a distance function its derivative is the
velocity function.
Find equation of a tangent line.
Find values at which f’(x) = 0. What does this about the graph of y = f(x) at such points?
Given a distance function for some object projected upward or the distance a vehicle travels after braking,
find its instantaneous velocity.
Find when the velocity is 0.
Find the height of the projected object when the velocity is 0; or in the case of the braking vehicle, find,
how far it travels before stopping.
Know the relationship between area and definite integral.
Find value of a definite integral using the Fundamental Theorem of Calculus.
You will be given the derivative formulas and antiderivative formulas.
The Soundex directions will be given.
Directions for check digit schemes other than for Postnet and ISBN will be given if needed
