Howdy,

I've been given a question about a trigonometric graph and I can't make sense of it so if you can help I will massage your face*

Question A states 'Plot the graph for Y = sinX for -2π ≤ x ≤ 2π'. So I went to Wolfram Alpha and plotted it here.

But the second question states 'Describe the curve in terms of its amplitude and period' and beyond saying it goes up and down I have no idea what I should be writing.

Any help is appreciated **

* not true

** very true
