the question:

What is your problem? Just put 0 in for x and count the values. Sec is 1/cos.

3. anonymous

sub sub it in, no where do you divive by zero

4. anonymous

sec(0) = 1/ cos(0) = 1/1 =1

5. anonymous

also know that tan(-5pi)=0

6. anonymous

once you sub it in it just simplifies down to $5\pi$ as the answer
