First define and output a vector x with the following values: −180°, −150°, −120°, −90°, −60°, −30°, 0°, 30°, 60°, 90°, 120°, 150°, 180°
Then, calculate and output y = 7 + 4 sin^2 (?) + cos(?).
Use shorthand notation to define x and element-by-element calculations to compute y.
Finally, compute and output the mean of the values in y

Is this a homework assignment?
MATLAB allows you to perform element-wise calculations on arrays using dot notation prior to the mathematical operator.https://www.mathworks.com/help/matlab/matlab_prog/array-vs-matrix-operations.html
Also, while most trigonometeric functions default to solve using radians they also have counterparts for solving using degrees.https://www.mathworks.com/help/matlab/trigonometry.html
