Invalid use of operator

Completely new to coding...I put in this
\draw plot[domain=0:7, samples=200] (\x, {0.5*sin(deg(2*pi*\x))});. And Matlab says invalid use of operator what am I doing wrong, it might help if the program would highlight what it doesn't like...Thanks

As Rik mentioned, this is not the correct language. MATLAB (like other programming environments/languages) has a strict syntax that you need to learn in order to use it.
I'm guessing at what you're trying to do, but a valid MATLAB command would be in the form of:
x = linspace(0, 7, 200);
y = 0.5 * sin(2*pi*x);
plot(x, y)
The error invalid use of operater came about because you were using the \ operator in a non-prescribed manner (in a way different than the way MATLAB defines the usage of the \ operator).
If you want to do more than just the simple plot command, then I would echo @Rik's advice to use the Onramp tutorial. It's slow going at first, but with great benefits once you learn it!

You need to specify MATLAB in your request to chatbot. Something like "Write a MATLAB program to draw a sine wave" and you should get something like this:
x = linspace(0, 7, 200);
period = pi/2;
y = 0.5 * sin(2 * pi * x / period);
plot(x, y, 'b-', 'LineWidth', 2)
fontSize = 20;
xlabel('x', 'FontSize', fontSize);
ylabel('y', 'FontSize', fontSize);
title('Sine Wave', 'FontSize', fontSize);
grid on;

This is not Matlab code. What language is this?
If you have trouble with Matlab basics you may consider doing the Onramp tutorial (which is provided for free by Mathworks).
