calculate the value of the expression s = 5 * cos(abs(2 * y)) in matlab

To calculate the value of the expression s = 5 * cos(abs(2 * y)) in MATLAB, you can follow these steps:

1. Define the value of y:

main.m
y = 1; % replace 1 with the desired value of y

2. Calculate the expression:

main.m
s = 5 * cos(abs(2 * y));

Here, we use the cos function to calculate the cosine of a value, the abs function to calculate the absolute value of a number, and basic arithmetic operations to evaluate the expression.

You can replace y with any desired value. After executing these steps, the variable s will contain the calculated result.

Note that in MATLAB, trigonometric functions expect the input in radians. If you are working with degrees, you may need to convert the values using the deg2rad function.

main.m
y_degrees = 45; % replace 45 with the desired value of y in degrees
y = deg2rad(y_degrees); % convert y to radians
s = 5 * cos(abs(2 * y)); % calculate the expression
