1. The problem statement, all variables and given/known data i understand how to find the period of a trig equation... (either 2pi/|b| for sin and cos or pi/|b| for tan etc. but i do not understand what information the period tells me.. 2. Relevant equations alright for example.. if my problem is y= 4sin2x 3. The attempt at a solution the period in the above solution would be pi... correct? so what does that tell me?????
