        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. 


They ask to find an exact value of tan%2817pi%29.


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


Therefore, tan%2817pi%29 = tan%280%29 = 0.    ANSWER

Solved correctly, with complete explanations.
