Graph the sine function for one complete cycle from 0 to 2π.

The graph of the sine function from 0 to 2π is a wave that starts at (0,0), peaks at (π/2,1), crosses the x-axis at (π,0), reaches a minimum at (3π/2,-1), and returns to (2π,0).

The graph oscillates between (0,0) and (2π,1) without crossing the x-axis.

The sine function peaks at (π,1) and has a minimum at (π/2,-1).

The graph of the sine function is a straight line from (0,0) to (2π,0).
