# Math Help - sinusoidal functions

1. ## sinusoidal functions

How to determine the phase shift of a sine function that has an amplitude of 3, period of pi, vertical translation 1 up, and pass through the point ( pi/3, 1)? Please help, thanks.

2. You have $y=3 \sin 2(x-b)+1$

sub $\left(\frac{\pi}{3},1 \right)$ to find $b$
