MATLAB CODE!!!

Problem 4: Plot the functions sin(t), sin(t), and ) over the interval [0, 2] using equally spaced points with step size 0.05 on three sub-figures in a column. Note that each figure must be square without being stretched to one direction. In plots, x-axis range must be [0, 2 and y-axis range should be appropriate for the respective data. Use different line colors and symbols for each c cos(t) function. Add the title, a grid, axis labels, and texts "sin(t)y", "sin(t)2"', and suso" near each corresponding curve “sin(t), cos(t) 20 Problem 5: Repeat Problem 4 by plotting the given three functions with 3 different figures, and arrange them horizontally. Label them appropriately. 10 Problem 6: Present on the same graph the function f(x)=log,o(x) and f(x)=log,o(x--/x) between 1 and 10 using Eplot commands. Specify the appropriate values for both x-axis and y- axis. Add legends, a grid, title, and labels for both x and y axes. 20 Problem 7: Draw an exact 2-D hexagon of any size and fill the interior of the object with any color. Label every corner with its own coordinate and write "hexagon" in the middle. 20

FIRST QUESTION SOLVED

1. MATLAB CODE

t=0:0.05:2*pi;
x1=sin(t); %% functions defined
x2=(sin(t)).^2;
x3=tan(t);
subplot(3,1,1)   
xlabel('time');
ylabel('amplitude')
title('sin(t)')
plot(t,x1,'o') ; % plot some data
set(gcf, 'Position', [50, 50, 270, 550]) %% figure resized
subplot(3,1,2)
xlabel('time')
ylabel('amplitude')
title('sin^2(t)')
plot(t,x2,'r') ; % plot some data
set(gcf, 'Position', [50, 50, 270, 550])
subplot(3,1,3)
xlabel('time')
ylabel('amplitude')
title('sin(t)/cos(t)')
plot(t,x3) ; % plot some data
set(gcf, 'Position', [50, 50, 270, 550])
