I won't bother making a new thread every time I post. I'll just post my math questions here if that's alright...

So we're doing sinusodal functions and

**the question reads:**Below are mapping rules for transformations of y=sinx . Determine the equation in standard form, equation of sinusodal axis, amplitude and period.

a) (x, y) ---> (1/3x - 10°, -2y)

So for standard form, I have y= -2sin3(x+10°). But what's the difference between Standard form and

*equation of the sinusodal axis*? That's my main question.

Also: Amplitude = 2, Period = 120°

I think...

Thank you

Edit: I got the answer. It was simply asking for where the sinusodal axis was located on the graph. So the equation for this one would be y=0. Pretty easy actually, just sounded confusing on the page.
