thanks for all the help. i was told by tutor the frequency is .159 Htz, so it takes 6.28 seconds to do a cycle. Does this make any sense?

Without a set of units to the number, this is difficult to answer.
Frequency is usually defined in science... in context of a problem. In terms of electromagnetic and sound waves... the frequency is the speed of the wave divided by its period.
f = v/p
p = v/f
fp = v
I cannot say that a generic sine wave has a frequency, as it just sits there on my graphing paper or calculator screen.
Frequency is defined as a number of units per number of other units. Typically referring to a rate over time. The Hertz for example are a unit convertible to (1/sec, or "per seconds") and refers to the number of cycles of something (like wave-forms) per second. Frequency need not be the same for all situations... it could be "number of vistiors per event".

For the sine function, period X frequency is always 2(pi), so if the period is 1, then the frequency is 2(pi). You can take that to the bank!!

Period T = 1.
Frequency w = ?
===============
w * T = 2 * Pi
w = 2 * Pi / T = 2 * Pi / 1 = 2 * Pi = 2 * 3.14 = 6.28

I believe the equation goes 1/f=PERIOD ..so if the period is 1, the frequency is also 1.

"1" is not a period. It is just a number. Did you perhaps mean "1 second"? If so, the frequency is 1 Hz.
