% Define the function and its Maclaurin series expansion

f = @(x) exp(x);

m6 = @(x) 1 + x + x.^2/2 + x.^3/6 + x.^4/24 + x.^5/120;

m8 = @(x) 1 + x + x.^2/2 + x.^3/6 + x.^4/24 + x.^5/120 + x.^6/720 + x.^7/5040;

m10 = @(x) 1 + x + x.^2/2 + x.^3/6 + x.^4/24 + x.^5/120 + x.^6/720 + x.^7/5040 + x.^8/40320 + x.^9/362880;

% Define the range of x values to plot

x = linspace(-3, 3, 100);

% Plot the function and its Maclaurin series expansions

plot(x, f(x), 'LineWidth', 2); hold on;

plot(x, m6(x), 'LineWidth', 2);

plot(x, m8(x), 'LineWidth', 2);

plot(x, m10(x), 'LineWidth', 2);

% Add a legend and labels

legend('f(x)', 'Maclaurin series (6 terms)', 'Maclaurin series (8 terms)', 'Maclaurin series (10 terms)');

xlabel('x');

ylabel('y');

title('Function f(x) = e^x and its Maclaurin series expansion');
