      1. To verify graphically:

         

        The graph shows the two eqauations: y equals secant x times sine x and y equals tangent x. The two equations have undefined values at –3 pi divided by 2, –pi divided by 2, pi divided by 2, 3 pi divided by 2, and so on, and overlap completely over the domain of –2 pi radians to 2 pi radians.



      2. The graph shows the two eqauations: y equals the secant of x times the cotangent of x times the sine of x squared and y equals the sine of x. The two functions overlap.


      3. The graph shows the two eqauations: y equals the secant of x times the cotangent of x times the sine of x squared and y equals the sine of x. The two functions overlap.
