Form the operator $\hat{A}^2$ if $\hat{A}=d^2 / d y^2+3 y(d / d y)-5$. Be sure to include an arbitrary function on which the operator acts.

Briefly describe how the && operator works.

Devise an explanation for the obvious relation between the last two terms of the Laplacian operator, in spherical polar coordinates, and the operator for the square of the magnitude of the orbital angular momentum.

An operator may be _______ to work with a specific class.

Insert an adjective clause to modify the noun or pronoun in italics.
Our first assignment,_____, was due on Tuesday.

Given:

int num1, num2, newNum;
double x, y;

Is the assignment x = x + y - 5; valid? If it is not valid, state the reason.

Underline the correct pronoun in parentheses in given of the following sentence.
The recorder for the group assignment is (she, her).

In a college clas s, 70% of the tudents who receive an "A" on one assig nment will receive an "A" on the next assignment. On the other hand, 10% of the students who do not receive an "A" on one assig nment will receive an "A" on the next assignment. Find and interpret the steady state matrix for this situation.

Is there an assignment of true/false values for the variables p, q, r, s, and t such that the formula $[(p \vee q) \wedge(\neg p \vee \neg r)] \rightarrow[(s \vee t) \wedge(\neg s \vee \neg t)]$ takes the value true? If so, find such an assignment. If not, explain why not.

What is returned by the function that overloads the operator << for a class?

Accessing a single character out of a string is called: a) slicing b) concatenation c) assignment d) indexing

If the contract creating the rights prohibits assignment, the parties may still assign them. True or False?

Imagine tossing a fair coin 3 times. What is the assignment of probabilities to outcomes in this sample space?

(a) For an eight-state sequential circuit using three flip-flops, give three state assignments that assign 000 to $S_0$ and are equivalent to a straight binary assignment. (b) Give three state assignments that assign 111 to $S_0$ and are not equivalent to a straight binary assignment or to each other.
