Question

USING MATLAB

write a script that creates eight subplots(4x2). In each one, graph the values of sin(n(pi)x), where -1 <=x<=1, with an interval of 0.05 for n = 1 to 8.

there is no parenthesis on pi. I just didn't want to make it look like (npix) so it wouldn't be confusing to read.

Answer 1

Following is the code in eight_sines.m :

%
% Define the x-vector.
% 
x = -1 : 0.05 : 1;

%
% We use a loop to draw the eight plots.
%
for n = 1 : 8
    
    %
    % Determine the y-vector.
    %
    y = sin(n .* pi .* x);
    
    %
    % Draw the plot.
    %
    
    % 
    % Choose the position.
    %
    subplot(4, 2, n);
    
    plot(x, y);
    title(['n = ', num2str(n),]);
    
    grid on;
    hold on;
    
end

Following is the run :
