Graph is inserted. Observe period 2/3pi23π, choosing x in [0, 2/3pi]x[0,23π], for one period. y ranges between +-(amplitude}=+-1±(amplitude}=±1, between the ends [0, 0] and [2/3pi, 0][0,0]and[23π,0].

Explanation:

y = sin (3x+pi)=-sin (3x)y=sin(3x+π)=sin(3x)

The graph is inserted.

The period of this sine wave is (2pi)/32π3.

The amplitude is 1.

Sample period: x in [0, 2/3pi]x[0,23π]

Ends for this full wave: (0, 0) and (2/3pi, 0)(0,0)and(23π,0)
