Chapter 1.7, Problem 12ES

(a) Use a calculating utility set to radian measure to make tables of values of $y={\sin }^{-1}x$ and $y={\cos }^{-1}x$ for $x=-1,-0.8,-0.6,\dots .,0,0.2,\dots ,1$ . Round your answers to two decimal places.

(b) Plot the points obtained in part (a), and use the points to sketch the graphs of $y={\sin }^{-1}x$ and $y={\cos }^{-1}x$ . Confirm that your sketches agree with those in Figure $\mathrm{1.7.1}$ .

(c) Use your graphing utility to graph $y={\sin }^{-1}x$ and $y={\cos }^{-1}x;$ confirm that the graphs agree with those in figure $\mathrm{1.7.1}$ .
