how to calculate the cosine of an angle in degrees in matlab

To calculate the cosine of an angle in degrees in Matlab, first convert the angle to radians using the deg2rad() function. Then, use the built-in cos() function to calculate the cosine of the angle. Here's an example:

main.m
angle_degrees = 45; % input angle in degrees
angle_radians = deg2rad(angle_degrees); % convert to radians
cosine_value = cos(angle_radians); % calculate cosine
disp(cosine_value); % display the result

Output:

main.m
