As a junior congress person you have been asked to help promote a bill to allow casino gambling in your state. There is much opposition to this bill. Using distributive bargaining, discuss the pros and cons which might arise toward the passing or defeating of this bill. A 300 word response must be posted to the discussion forum. 

Given the following scenario create an ERD for the Bookstore.

I sell books and would like to create a database for my books and transactions. At this time I am not keeping track of supplier information. Many times customers come in asking what books a special author has written. Other times the customer wants books from a certain publisher or even a particular genre. Some of my books are hard cover and some are soft cover. I do not have any digital books.

**Remember the only foreign keys I should see in the ERD are for the bridges.

Here’s a link on how to do it.  Please do not copy and make your own.

In this project you will create a basic console based calculator program.

The calculator can operate in two modes: Standard and Scientific modes. 

The Standard mode will allow the user to perform the following operations: 

(+, -, *, /) add, subtract, multiply, and divide

The Scientific mode will allow the user to perform the same functionality as the Standard 

add, subtract, multiply, and divide (+, -, *, / ) plus the following: 

sin x, cos x, tan x. (sin x, cos x, tan x)

The calculator should be able to perform addition, subtraction, multiplication, and division of two or more numbers but perform sin x, cos x, and tan x of one number only (the number is in radians). 



1. The calculator program will first ask the user for the mode to operate in (Standard or Scientific)



      Sample Output: 

      Enter the calculator mode: Standard/Scientific?



 Scientific



2. The program should then ask the user for the operation to execute (+, -, *, /, sin x, cos x, tan x)



      Sample Output for Standard mode:

      The calculator will operate in standard mode.

      Enter '+' for addition, '-' for subtractions, '*' for multiplication, '/' for division



      Sample Output for Scientific mode:

      Enter '+' for addition, '-' for subtractions, '*' for multiplication, '/' for division, 'sin' for sin x, 'cos' for cos x, 'tan' for tan x:

      sin



2a. If the user enters an invalid operator, output a message telling the user the input is invalid and re-prompt the user for the operation again.

      Sample Output for Scientific mode:

      Enter '+' for addition, '-' for subtractions, '*' for multiplication, '/' for division, 'sin' for sin x, 'cos' for cos x, 'tan' for tan x:

 division

      Invalid operator division

      Enter '+' for addition, '-' for subtractions, '*' for multiplication, '/' for division, 'sin' for sin x, 'cos' for cos x, 'tan' for tan x:



 +



3. In order to know how many times the user will need to perform the operation, prompt the user for the number of floating point values they want to enter (All numbers in this program are double), then ask the user to enter the numbers. 



      Sample Output:

      How many numbers do you want to add?:

 3

      Enter 3 numbers:

 4

 35

 9



In this example the calculator will calculate 4 + 35 + 9. The calculated result will be 48. 



The calculator should be able to perform the following operations:



      2+3 = 5

      2+6+1+1+1 = 11

      1-2-90 = -91

      10*2*3 = 60

      10/2/5 = 1

      cos(0) = 1

      sin(0) = 0

      tan(0) = 0



Note: This calculator does NOT support multiple operations of varying operators in the expressions like: 10+2-8

Note: Multiple numbers are only acceptable for the operations of (+, -, *, / ) not for (sin,cos,tan)



4. Display the result

      Sample Output:

      Result: 50.0



5. Finally, output the result to the user and ask the user if he/she wants to start over. 

      Sample Output:

      Do you want to start over? (Y/N)

      Y



      Full Sample Output:

      Enter the calculator mode: Standard/Scientific?

      Scientific

      Enter '+' for addition, '-' for subtractions, '*' for multiplication, '/' for division, 'sin' for sin x, 'cos' for cos x, 'tan' for tan x:

 addition

      Invalid operator addition

      Enter '+' for addition, '-' for subtractions, '*' for multiplication, '/' for division, 'sin' for sin x, 'cos' for cos x, 'tan' for tan x:

 +

      How many numbers do you want to add?:

 3

      Enter 3 numbers:

 4

 35

 9

      Result: 48.0

      Do you want to start over? (Y/N)

Y

      Enter the calculator mode: Standard/Scientific?

Scientific



      Enter '+' for addition, '-' for subtractions, '*' for multiplication, '/' for division, 'sin' for sin x, 'cos' for cos x, 'tan' for tan x:

cos



      Enter a number in radians to find the cosine

 0

      Result: 1

      Do you want to start over? (Y/N)

N
