(a) Find the general solution of the system: $y_1' = y_1 + y_2$ $y_2' = -2y_1 + 4y_2$. (b) Find the solution of the following initial value problem: $y_1' = -y_1 + 2y_2$ $y_2' = 2y_1 - y_2$ $y_1(0) = 3$, $y_2(0) = 1$. (c) Find the general solution of the system: $y_1'' = 2y_1 + y_1'$ $y_2'' = 2y_2 + y_1'$.

i... 2. Summation Of Numbers (using Nested While Loops) Part A: The program will calculate and display the total of all numbers up to a specific number (entered by the user). Only positive numbers are allowed. Examples: When 5 is entered the program will calculate the total as 1+2+...+5 and display 15. When 2 is enterered the program will calculate the total as 1+2 and display 3. Here is an example of one run of the program. Enter a positive integer number: 0 wrong input, try again. Enter a positive integer number: -2 wrong input, try again. Enter a positive integer number: 5 The sum from 1 to 5 is: 15 Tips: The solution of Part A consists of two loops (not nested!). one for the input validation (only positive integer numbers allowed), followed by a second one for the calculation of the total (use a for loop, do not use the sum function).
