Mathematical Sciences

Each course in the Humanities category of the General Education Program will provide instruction and guidance that help students to:

Obj. 1) Engage the human experience through the interpretation of culture.

Obj. 2): Become aware of the act of interpretation itself as a critical form of knowing in the humanities.

Obj. 3) Make academic arguments about the human experience using reasons and evidence for supporting those reasons that are appropriate to the humanities.

Each course in the Mathematial Sciences category
of the General Education Program will provide instruction and
guidance that help students to:

Obj. 1) Improve and refine mathematical problem-solving abilities.

Outcome 1: Use the techniques of partial differentiation to explore the properties of a function of two or more variables

Outcome 6: Carry out numerical simulations and mathematical analyses of a model

Outcome 6: Carry out numerical simulations and mathematical analyses of a model

Outcome 1 will be assessed through WebAssign homework, in class work, and exam questions similar to those below.

Example 1: The volume V (measured in cubic metres) of a certain amount of gas is determined by the temperature T (measured in Kelvin) and the pressure P (measured in megapascals) by the formula V = 0.08(T/P). Calculate the values and units of dV/dP and dV/dT when P = 0.5 MPa and T= 300 K. (Give exact answers.) Then give an interpretation of these values in the context of the problem.

Example 2: U.S. postal rules require that the length plus the girth of a package cannot exceed 84 inches in order to be mailed. Find the exact dimensions of the rectangular package of greatest volume that can be mailed.

Example 3: In economics, substitute goods are two products that are similar or comparable to each other, think iPhones and Nexus phones. On the other hand, complementary goods are products that go together, think iPhones and Apple Watches.

1. Suppose we have two products that are substitute goods where product 1 costs $x

per unit and product 2 costs $y per unit. If f(x,y) is a function that models the number

of units of product 1 that are sold, what would the signs of df/dx and df/dy be? Why?

2. Now suppose instead that out two products are complementary goods with x, y, and f(x,y) defined exactly as above. What would the signs of df/dx and df/dy be now? Why?

Outcome 6 will be assessed through WebAssign homework, in class work, and exam questions similar to those below.

Example 1: (a) Given the initial value problem y' = 10 − y, y(0) = 1, use Euler's method with h=1/3 to estimate the value of y(1). (Give your answer correct to at least three decimal places.)

(b) Using separation of variables, solve the initial value problem

y' = 10 − y, y(0) = 1.Use this solution to find the exact value of y(1). (Give your answer correct to at least three decimal places.)

(c) Compare the two answers.

Example 2: A certain hormone is produced by an endocrine gland, causing its concentration to increase at a constant rate of A mg/L. The hormone is metabolized by the liver, with the rate of elimination being proportional to the concentration of the hormone. The constant of proportionality in this relationship is given by the (positive) constant k. The concentration of the hormone at time t is written as y(t). At time t = 0, a patient comes off a drug treatment that had blocked production of the hormone. (So, at that time, they do not have any of the hormone in their body.) Their doctor finds that the initial rate of increase of their hormone concentration is 0.625 mg/L/hour and that, in the long run, the concentration approaches 4.25 mg/L. After how long would the patient's hormone concentration have reached half of its long-term level? At what rate would the level of hormone be increasing at that time?

Outcome 2 will be assessed through WebAssign homework, in class work, and exam questions similar to those below.

Example 1: A monopolist manufactures and sells two competing products, call them I and II, that cost $43 and $32 per unit, respectively, to produce. The revenue from marketing x units of product I and y units of product II is R(x, y) = 111x + 124y − 0.04xy − 0.1x2 − 0.2y2. Find the exact values of x and y that maximize the monopolist's profits and the maximum profit she would earn. Justify why this is a maximum and not a minimum.

Example 2: The amount of space required by a particular firm is given below, where x and y are, respectively, the number of units of labor and capital utilized.

f(x, y) = 1000sqrt(6x^2+y^2). Suppose that labor costs $480 per unit and capital costs $40 per unit and that the firm has $4000 to spend. Determine the amounts of labor and capital that should be utilized in order to minimize the amount of space required.

Outcome 5 will be assessed through WebAssign homework, in class work, and exam questions similar to those below.

Example 1: A student must learn M unfamiliar words for an upcoming test. The rate at which the student learns is proportional to the number of items remaining to be learned, with constant of proportionality equal to k. Initially, the student knows none of the words. Let y(t) stand for the number of the words that the student knows at time t.

(a) Write down the right hand side of the differential equation satisfied by y.

(b) What is the initial value of y?

Example 2: A certain drug is administered intravenously to a patient at the continuous rate of 5 mg per hour. The patient's body removes the drug from the body at a rate that is proportional to the amount of drug in the blood. Write the amount of drug in the blood as y and let the positive constant of proportionality for the removal rate be k. Write a differential equation that is satisfied by the amount of drug in the blood.

Outcome 6 will be assessed through WebAssign homework, in class work, and exam questions similar to those below.

Suppose that there are 150 words to be learned and that k = 0.5 per hour for this student. Recall that the solution to

y' = k(M − y) with y(0) = 0 is given by y(t) = M(1 − e^{−kt}).
