What is a reasonable estimate for each value from the graph? Check your estimate with a calculator.
sin 2
The sine function reaches its maximum value of 1 at
Check
How accurate should your estimate be?
The y-values range from
sin π
The sine function crosses the x-axis at π, so sin π = 0.

The graph of a sine function is called a sine curve. By varying the period (horizontal length of one cycle), you get different sine curves.
