-----------------------------------
compute the given function value without a calculator.
theta =11pi/6 and cos(11pi/6)
------------------------------------

You could simply say, "find the value of cos%2811pi%2F6%29, without using a calculator."

See on the unit circle, 11pi%2F6 corresponds to -pi%2F6. The sign of both those angles are the same (both are positive). Already recognize that cosine of this/these is sqrt%283%29%2F2.
