how to 2d plot simple ?

x=deg2rad(17)

tan(x/2) =(1-cos(x))/(sin(x))

You only defined three single values. What are you trying to plot ?

Hi Nx Mathlab,

I assume that you would like to plot a 2D graph using the tan(x/2) defination but with a range of angles. If so refer to the code below -

% Define a vector of angles in degrees
angles_deg = 0:1:360; % Angles from 0 to 360 degrees

% Convert the angles to radians
x = deg2rad(angles_deg);

% Calculate the tangent values
tan_x_over_2 = (1 - cos(x)) ./ sin(x);

% Create a figure
figure;

% Plot the data
plot(x, tan_x_over_2); 

% Add labels and title
xlabel('Angle (radians)');
ylabel('tan(x/2)');
title('2D Plot of tan(x/2) vs. Angle');

% Display the grid
grid on;

This code will generate angles from 0 to 360 degrees and, using the definition of tan_x_over_2 , it will plot the angles versus the tan(x/2) value on a 2D graph.

Hope this helps!
