I cannot solve this problem. Please show all work and explain why on each step. I can get up to Tan(11pi/12)= pi/4+2(pi/3). Unsure of 2(pi/3) refrence triangle quadrant. When using 2nd quadrant for 2(pi/3) my equation looks like this.

1+((-square root of three)/1) / 1-(1)((-square root of three)/1)

What is a number called when it is infinitely small or large (not exactly but kind of, see the examples to get what i mean) but still exists?
For example the smallest number between 0 and 1 or the maximum kinetic energy a ball about to hit the ground will get.

I live in North Cyprus and the ebb and flow of the tide here seems really small (almost non-existent in fact). Does anyone out there live somewhere similar or somewhere totally opposite where tidal change is really noticeable.
