Use MATLAB to plot the functions u = 2 log10(60x + 1) and υ = 3 cos(6x) over the interval 0 ≤ x ≤ 2.

Use MATLAB to plot the functions u = 2 log10(60x + 1) and υ = 3 cos(6x) over the interval 0 ≤ x ≤ 2. Properly label the plot and each curve. The variables u and represent speed in miles per hour; the variable x represents distance in miles.

Expert Solution

Write the functions,

u = 2log10(60x + 1)

v = 3cos(6x)

The domain of the functions is 0 ≤ x ≤ 2.

Two-dimensional line plots can be created using the ‘’plot function’’.

Firstly define displacement (x) as a vector, next define the function u and then plot the given function by using plot ().

Use hold command to add another plot u to an existing figure.

Input the following into Matlab:

>> x=0:0.01:2;

u=2^log10(60*x+1);

plot(x,u)

hold on

v=3*cos(6*x);

plot(x,v,’r:’)

ylabel(‘Speed(mi/hr)’), xlabel(‘Distance x (mi)’)

legend(‘u’,’v’)

Note: 'r:' string is used for red dotted line.

The output of the plots is as shown below:

Write the functions,

u = 2log10(60x + 1)

v = 3cos(6x)

The domain of the functions is 0 ≤ x ≤ 2.

This code is to be written in Matlab. Write a function that will plot cos(x) for x values ranging from -pi to pi in steps of 0.1, using black *'s. It will do this three times across in one Figure Window, with varying line widths. If no arguments are passed to the function, the line widths will be 1, 2, and 3. If on the other hand, an argument is passed to the function, it is multiplier for these values....
