A few question i am stuck on:

1)$\displaystyle y=Atan(nt)$ find A and n using the information provided

Asymptotes have equation $\displaystyle t=(2k+1)\frac{\pi}{6}$where k=>Z

when $\displaystyle t=\frac{\pi}{12},y=5$

2)$\displaystyle y=Asin(nt+e)$

Range = [-2,2]

Period=6

When t=1,y=1

I have found what A and n is however i don't know how to find e.

P.S
