how to calculate the secant of an angle in matlab

The secant of an angle is defined as the reciprocal of the cosine of the angle. In MATLAB, you can calculate the secant of an angle using the sec() function. Here's an example code for computing the secant of an angle in MATLAB:

main.m
% Define the angle in radians
theta = pi/4;

% Compute the secant of the angle
secant_theta = 1/cos(theta);

% Alternatively, you can use the sec() function
secant_func_theta = sec(theta);

% Display the results
fprintf('The secant of %f radians is %f\n', theta, secant_theta);
fprintf('Using the sec() function, the secant of %f radians is %f\n', theta, secant_func_theta);

In this example, we first define an angle theta of 45 degrees (in radians) using the pi/4 expression. Then we compute the secant of the angle using the reciprocal of the cosine of theta (1/cos(theta)) and also using the sec() function (sec(theta)). Finally, we display the results using the fprintf() function.
