Question

Do exercise 8.4 on page 194 of the textbook but do not create tables and do not sketch the results by hand. Instead, save the computed values in vectors and plot the results as indicated at the end of the description of the exercise.

NOTE: The temptation for the average programmer (especially in the context of a chapter titled ‘Loops") is to do this exercise using FOR loops. DON'T DO IT! Use MATLAB®'s vectorization capability to make this exercise very simple.

Name your program "ex8p4_LastName.m".

8.4 Winte a program to compute a table of the function xsin 2 over the (closed) interval using increments in x of (a) 0.2, (b) 0.1, and (c) 0.01. Use your tables to sketch graphs of f(x) for the three cases (by hand), and observe that the tables for (a) and (b) give totally the wrong picture of fx) Cet your program to draw the graph of f(x) for the three cases, superimposed

Write a program to compute a table of the function:

f (x) = x sin ­= [(pi(1 + 20x))/2]

over the (closed) interval [−1, 1] using increments in x of (a) 0.2, (b) 0.1, and (c) 0.01. Use your tables to sketch graphs of f(x) for the three cases (by hand), and observe that the tables for (a) and (b) give totally the wrong picture of f(x).
Get your program to draw the graph of f(x) for the three cases, superimposed.
