Sibanda 85 72 49 75 63
Use two-dimensional array to store the test scores, and a parallel one-dimensional array to store grades. Your program must contain at least the following functions: a function to read and store data into arrays, a function to calculate the average test score and grade, and a function to output the results. Have your program also output the class average

[solved] – Question 95808
Consider the parabola defined by y = x
2 − 2x − 1. The distance d(x) from the origin
(0, 0) to a point (x, y) on the parabola is given by
d(x) = q
x
2 + (x
2 − 2x − 1)
2
.
(a) Write a MATLAB program and function M-file to plot d(x) for −2 ≤ x ≤ 4. Also use the
function M-file and the fminbnd command to find (and display) the point (xmin,ymin) on
the parabola that is closest to the origin and display the minimum distance (i.e., the distance
from the origin to the point (xmin,ymin)).
(b) Write a MATLAB program using the fzero command to find the point(s) on the parabola at
distance 4 from the origin.

[solved] – Question 95809
Consider the function f(x) = e
x where e = 2.718 . . . is the base of the natural logarithm
(ln = loge
), sometimes known as Napier’s constant. For x close to 0, e
x
can be approximated by a
finite Taylor series:
e
x ≈ s = 1 + x +

where p is a positive integer.
(a) Write a MATLAB program with a for loop to compute (and display) the approximation s of
e
x and the difference d = s − e
x
for p = 1, 2, . . . , num where x and num are entered by the user.
Your program should use format long e and display the values s and d in two columns
with appropriate headings. (Recall that e
x
can be computed in MATLAB using exp(x).)
(b) Run your program with x = 0.5 and num = 10.
(c) Use your program to find the smallest value of p for which the difference s − e
0.5 is less than
10−14 in absolute value.

[solved] – Question 95886
Write a program Checkers that takes one number (X) entered by the user and prints out a two dimensional X-by-X checkerboard pattern with alternating spaces and asterisks, like the following 4-by-4 pattern. Remember, the user should be able to enter any value for X and the output should be an X-by-X checkerboard of alternating spaces and asterisks.
