Write a Python program that verifies the formula with the help of the Python Math module. Note that the trigonometric functions in the module act on the angles in radians. Your program should perform the following steps 3 times:_____.
1. Pick a random number between 0 and 180 degrees representing an angle in degrees, say Dangle
2. Convert the angle from degrees to radians, say Rangle
3. Use the Math module to find and print the values of sin(Rangle) and cos(Rangle), and
4. Compute and print the value of the above expression: sin^2(Rangle) + cos^2(Rangle).
You can then visually verify if the result printed is 1 (or close to it).
Hint: angle_in_radians = (angle_in_degrees * Pi)/180
Answers
Answer:
Written in Python
import math
import random
Dangle = random.randint(0,181)
pi = 22/7
Rangle = Dangle * pi/180
Rsin = math.sin(Rangle)
Rcos = math.cos(Rangle)
Result = Rsin**2 + Rcos**2
print("Result = "+str(Result))
Explanation:
The next two lines import math and random library respectively
import math
import random
This line generates a random integer between 0 and 180
Dangle = random.randint(0,181)
This line initializes pi to 22/7
pi = 22/7
This line converts angle to radians
Rangle = Dangle * pi/180
The next two lines calculate the sin and cosine of the angle in radians
Rsin = math.sin(Rangle)
Rcos = math.cos(Rangle)
This line implements sin^2 theta + cos^2 theta
Result = Rsin**2 + Rcos**2
This line prints the required Result
print("Result = "+str(Result))

The following example demonstrates a program that uses 3 levels of nested dictionaries to create a simple music library. The following program uses nested dictionaries to store a small music library. Extend the program such that a user can add artists, albums, and songs to the library. First, add a command that adds an artist name to the music dictionary. Then add commands for adding albums and songs. Take care to check that an artist exists in the dictionary before adding an album, and that an album exists before adding a song.

What formatting changes do spreadsheet applications permit in the rows and columns of a spreadsheet?
Row and Column Formatting Options
Formatting rows and columns is similar to cell formatting. In an OpenOffice Calc spreadsheet, you can format data entered into rows and columns with the help of the Rows and Columns options. You can insert rows and columns into, or delete rows and columns from, a spreadsheet. Use the Insert or Delete rows and columns option on the Insert tab. Alternatively, select the row or column where you want new rows or columns to appear, right-click, and select Insert Only Row or Only Column options.
You can hide or show rows and columns in a spreadsheet. Use the Hide or Show option on the Format tab. For example, to hide a row, first select the row, then choose the Insert tab, then select the Row option, and then select Hide. Alternatively, you can select the row or columns, right-click, and select the Hide or Show option.
You can adjust the height of rows and width of columns. Select Row and then select the Height option on the Format tab. Similarly, select Column, then select the Width option on the Format tab. Alternatively, you can hold the mouse on the row and column divider, and drag the double arrow to the position. You can also use the AutoFit option on the Table tab to resize rows and columns.

In this lab, you use what you have learned about parallel arrays to complete a partially completed C++ program. The program should:
Either print the name and price for a coffee add-in from the Jumpin’ Jive Coffee Shop
Or it should print the message Sorry, we do not carry that.
Read the problem description carefully before you begin. The file provided for this lab includes the necessary variable declarations and input statements. You need to write the part of the program that searches for the name of the coffee add-in(s) and either prints the name and price of the add-in or prints the error message if the add-in is not found. Comments in the code tell you where to write your statements.
Instructions
Study the prewritten code to make sure you understand it.
Write the code that searches the array for the name of the add-in ordered by the customer.
Write the code that prints the name and price of the add-in or the error message, and then write the code that prints the cost of the total order.
Execute the program by clicking the Run button at the bottom of the screen. Use the following data:
Cream
Caramel
Whiskey
chocolate
Chocolate
Cinnamon
Vanilla
Answers
A general outline of how you can approach solving this problem in C++.
Define an array of coffee add-ins with their corresponding prices. For example:
c++
const int NUM_ADD_INS = 7; // number of coffee add-ins
string addIns[NUM_ADD_INS] = {"Cream", "Caramel", "Whiskey", "chocolate", "Chocolate", "Cinnamon", "Vanilla"};
double prices[NUM_ADD_INS] = {1.50, 2.00, 2.50, 1.00, 1.00, 1.25, 1.00}
What is the program about?Read input from the user for the name of the coffee add-in ordered by the customer.
c++
string customerAddIn;
cout << "Enter the name of the coffee add-in: ";
cin >> customerAddIn;
Search for the customerAddIn in the addIns array using a loop. If found, print the name and price of the add-in. If not found, print the error message.
c++
bool found = false;
for (int i = 0; i < NUM_ADD_INS; i++) {
if (customerAddIn == addIns[i]) {
cout << "Name: " << addIns[i] << endl;
cout << "Price: $" << prices[i] << endl;
found = true;
break;
}
}
if (!found) {
cout << "Sorry, we do not carry that." << endl;
}
Calculate and print the total cost of the order by summing up the prices of all the add-ins ordered by the customer.
c++
double totalCost = 0.0;
for (int i = 0; i < NUM_ADD_INS; i++) {
if (customerAddIn == addIns[i]) {
totalCost += prices[i];
}
}
cout << "Total cost: $" << totalCost << endl;

For a given gate, tPHL = 0.05 ns and tPLH = 0.10 ns. Suppose that an inertial delay model is to be developed from this information for typical gate-delay behavior.
Assuming a positive output pulse (LHL), what would the propagation
delay and rejection time be?
Answers
The rejection time (time for the output to remain stable at low after input changes from high to low) is also 0.05 ns.
How to determine the delaysPropagation Delay:
The propagation delay (tPHL) is given as 0.05 ns (nanoseconds).
This represents the time it takes for the output to transition from a high to a low level after the input changes from a high to a low level.
Propagation Delay (tPHL) = 0.05 ns
Rejection Time:
The rejection time (tRHL) is the minimum time required for the output to remain stable at a low level after the input changes from a high to a low level before the output starts to transition.
Rejection Time (tRHL) = tPHL
Hence = 0.05 ns
Therefore, for the given gate and assuming a positive output pulse (LHL):

Emitter-Coupled Logic (ECL) is a type of digital logic circuit that was developed in the 1950s as a high-speed alternative to other forms of logic, such as TTL (transistor-transistor logic) and CMOS (complementary metal-oxide-semiconductor).
What is the technology?The input and output voltage swings in ECL are small (0.8 V), the input impedance is high, and the output impedance is low. The transistors are also never saturated. As a result, gate delays are short, transistor states change quickly, and fanout capability is high.
Therefore, ECL circuits use bipolar junction transistors (BJTs) as their primary active devices. These transistors operate in the "saturated" region, where they are biased to conduct heavily, which allows them to switch very quickly. The input signals to an ECL circuit are differential, meaning that they consist of two complementary signals that are opposite in polarity.
