Trigonometry: The basic MATLAB trigonometric functions are sin, cos, tan, cot, sec, and csc. The inverses, e.g., arcsin, arctan, etc., are cal- culated with asin, atan, etc. The same is true for hyperbolic functions. The inverse function at an2 takes two arguments, y and z, and gives the four- quadrant inverse tangent. The argument of these functions must be in radians. Calculate the following quantities: • sin, cos 7, and tan . • sin²+ cos² (Typing sin^2(x) for sin²r will produce an error). y = cosh²z-sinh²z, with z = 32m.
