These questions get nothing but a blank stare from me....kinda irritating really since I sort of like trigonometry.

Describe each of the following graphs of y. Give (a) its amplitude (if applicable),(b) its maximum and minimum (if applicable) and (c) its period.

If it has no amplitude, maximum or minimum, write none in the appropriate space.

1

$\displaystyle y=3\sin\frac{1}{3}x $

(a) 3(I think)

(b)no idea

(c) $\displaystyle \frac{2\pi}{\frac{1}{3}}$ (I hope)

2

$\displaystyle y=\tan 2A$

(a) No clue

(b) Maximum:none and Minimum: none

(c) I wish I knew...

Thank you muchly once again!!
