Question: This problem introduces the arccosine function, or inverse cosine, denoted by cos-1 on most calculators.
(a) Using a calculator set in radians, make a table of values, to two decimal places, of g(x) = arccos x, for x = -1, -0.8, -0.6,..., 0,..., 0.6, 0.8, 1.
(b) Sketch the graph of g(x) = arccos x.
(c) Why is the domain of the arccosine the same as the domain of the arcsine?
(d) What is the range of the arccosine?
(e) Why is the range of the arccosine not the same as the range of the arcsine?
