y= 2 - (5/2) sec( (2pi/5)x-4pi)
By what factor is the graph of this secant function being stretched horizontally?
I thought you're supposed to divide 2pi by 2pi/5:
2pi * 5/2pi =
10pi/2pi = 5
The correct answer was 2pi/5
Please help me understand this. I have a unit exam next week and a quiz I need to be studying for tomorrow.
