Thread: i need to graph a sine function.

Hello all! I'm really confused at how to plot the points of this sine function... read on!

THE QUESTION: Sketch the graph of the function by hand. use a graphing utility to verify your sketch (include two full periods).
I have to include the key points of the graph, the period and the amplitude

THE FUNCTION:

i calculated the period and amplitude (although I'm not certain if they're correct)

period: 2pi
amplitude: (1/2)


Thank you so much! please include your work! I need to learn how to do this! any explanations will be greatly appreciated...

never mind! i figured it out by myself
