Thank you for the opportunity to help you with your question!

To find the angle between 0 and 2pi that is coterminal with the given angle, we simply have to add or subtract 2pi until we get result between 0-2pi

i.e. we are adding 18 pi/3 = 6 pi = 3(2pi)

-14pi/3 + (18pi)/3

= 4pi/3

Please let me know if you need any clarification. I'm always happy to answer your questions.

Hello! Okay I think I understand..

So for 55pi/2

I followed your steps and did

55pi/2-pi26 = 3pi/2

is this correct? If so then I can do the rest of the problems now. :)
