how to calculate the cotangent of an angle in matlab

To calculate the cotangent of an angle in Matlab, you can use the cot function which takes an angle in radians as its input. Here's an example:

main.m
% Angle in degrees
theta = 45;

% Convert angle to radians
theta_rad = theta * pi/180;

% Calculate the cotangent
ctg = cot(theta_rad);

In this example, we first define the angle theta in degrees. We then convert it to radians using the formula theta_rad = theta * pi/180, and finally calculate the cotangent using the cot function.

Note that cot returns the reciprocal of tangent (1/tan), which means that if the tangent is zero, cot is undefined.
