OK, I have 2 problems that I did that I need to know if they are correct. Here they are:

1. Find the following graphs of y. Give the amplitude, its maximum and minimum and its period.

y= 3sin1/3x Amp=3 period=2pi/1/3=2pi*3/1=6pi

Max=c+a=0+3=3

Min=c-a=0-3=-3 Since there's no c value I put 0...is that correct?

2. Find Amp, Max and Min, period.

y=tan2x

Now, there's no amp, maxormin values, right? There's only its period which is: 2pi/2=pi

I hope you can follow my problems and let me know if they are correct.

Thanks!
