Question 60845
.
Using the periodic properties of trigonometric functions, find the exact value of the expression:
tan 17pi
~~~~~~~~~~~~~~~~~~~~~~~~



        Looking at the solution of the other person (@consc198) in his post,

        I see that he/she does not understand the meaning of the question. 

        So, it is not surprisingly that his/her solution is incorrect and irrelevant.


        I came to bring a correct solution.



<pre>
They ask to find an exact value of {{{tan(17pi)}}}.


tan() is a periodic function with period T = {{{pi}}}.


Therefore, {{{tan(17pi)}}} = {{{tan(0)}}} = 0.    <U>ANSWER</U>
