Briefly describe how the or 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.

Which of the following are legal C++ assignment statements?

a. a = 7;
b. 7 = a;
c. 7 = 7;

Prove that if $T$ is a unitary operator on a finite-dimensional inner product space $V,$ then $T$ has a unitary square root: that is, there exists a unitary operator U such that $T=U^{2}$

The __________ operator is used to dynamically allocate memory.

Show that the operator $\hat{p}^{\prime}$ obtained by applying a translation to the operator $\hat{p}$ is $\hat{p}^{\prime}=\hat{T}^{\dagger} \hat{p} \hat{T}=\hat{p}$.

A tour operator believes that the profit P, in dollars, from selling x tickets is given by P(x) = 35x - 0.25x². Using this model, what is the maximum profit the tour operator can expect?

Control:

if my_var % 2:
    if my_var**3 != 27:
        my_var = my_var + 4
    else:
        my_var /= 1.5 
else:
    if my_var <= 10:
        my_var *= 2
    else:
        my_var -= 2 
print(my_var)

(a) Find four values of my_var so each of the four assignment statements will be executed: each value should cause one assignment statement to be executed.

(b) Find four ranges of my_var values that will cause each of the four assignment statements to be executed.

What writing style did you use in an assignment you completed for another class?

Modify the expression calculator given below to convert an expression into reverse Polish notation. Hint: Instead of evaluating the top and pushing the result, append the instructions to a string.

Here is the algorithm:

If you read a number
 Push it on the number stack.
Else if you read a (
 Push it on the operator stack.
Else if you read an operator op
 While the top of the stack has a higher precedence than op
   Evaluate the top.
 Push op on the operator stack.
Else if you read a )
 While the top of the stack is not a (
   Evaluate the top.
 Pop the (.
Else if there is no more input
 While the operator stack is not empty
   Evaluate the top.

Evaluate the top:
Pop two numbers off the number stack.
Pop an operator off the operator stack.
Combine the numbers with that operator.
Push the result on the number stack.

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.

What’s the purpose of the scope resolution operator?

Use the Law of Syllogism to write a third conditional statement. If Mark's pen runs out of ink, then he must get a new pen to finish his assignment. If Mark must get a new pen to finish his assignment, then he must go to the store.

A ferry operator takes tourists to an island. The operator carries an average of 500 people per day for a round-trip fare of $20. The operator estimates that for each$1 increase in fare, 20 fewer people will take the trip. What fare will maximize the number of people taking the ferry?
