Okay, so i'm given a trig equation, and i want to pull out some information that i would need to graph it.
00:08
Before i do that, i'm going to rewrite this equation by factoring out the frequency.
00:15
That's the number that you're multiplying x by.
00:18
I want it outside parentheses.
00:20
That's going to give me x minus 7 plus 2.
00:25
Okay, so my amplitude, my amplitude is the number that i'm multiplying the function by.
00:31
So in this case, it's 8.
00:34
To get the period, i take 2 pi over the frequency.
00:41
In this case, that's 2 pi over 6...
