2nd Midterm Exam
|
1. Write a subroutine that calculates the position, velocity and acceleration of a body undergoing simple harmonic motion using the equations below:
position = asin (nt+ε)
velocity= nacos(nt+ε)
acceleration = -an2sin(nt+ε)
Use as starting values n= 3.14159265, ε=0, a=2.5. Test the program by specifying your own set of values.
2. Write a program that calculate 2x2 matrix multiplication by using the command matmul.
3. Write a program that reads the grades from "prices.txt" (contains 10 different prices of goods., and writes a file named "mean_prices.txt" that contains the arithmetic average of the grades and also print maximum and minimum prices to the screen either.
Prices txt is included to following values.
