I'm drunk and want to get back to the SB while this garbage HT Show is going on. Can you guys solve these questions fairly quickly? If so, I look at you guys/girls as gods among men.

1)Write a sine function for this:
Amplitude:8
Period: 5x
Phase shift 1/9
subtraction

2)Same question
Amplitude:5
Period: 4x
Phase shift: - 1/6
addition

>phase shift 1/9

1/9 of what? 1/9 degrees? 1/9 radians? 1/9 of the wavelength?

>Period: 5x
Again, 5x of what? 5x "normal" period?

Be more specific.

play around with this.

amplitude: factor before sin
period change: division/multiplication of your argument.
phase shift: addition / subtraction of your argument.

that's all you will get from me
