Is There A Megafunction For Arctan ?

Universities pay the fee.

I come from an University and come to this forum to exchange ideas with people experts in the field.

I can assure you that in the Universities not everybody is an expert on Altera FPGA design. As a consequence web resources and forums are very much used to improve the quality of the work.

Further, I think that many University people, such as young master thesis students, come to this forums to seek advices for their projects.

These students usually have access to many on-line journals such as IEEE.
