finding the exact value of
1.)y= cos inverse (-1) = 180 degrees
------------------------------
2.)y=arccot(-sqrt 3) = 150 or 210 degrees
----------------------------------
3.)y=tan inverse 1 = 45 or 225 degrees
-----------------------------
4.)y=sin inverse (-1) = 270 degrees
-----------------------------
5.)y=arctan(-1) = 135 or 315 degrees
-------------------------------
6.)y=tan inverse (-1) = 135 or 315 degrees
-------------------------------
7.)y=arcsec (2 sqrt (3)/3) = 30 or 330 degrees
