: : Is there any easy way to look at a graph that is a variation of the sine or cosine curve and be able to determine its equation,using the formula:y= asin(bx+c)+k?
: yes!
: the amplitude is |a|.
: the vertical shift is k.
: the phase shift (beginning of a cycle) is -c/b.
: the period (length of one cycle) is 2pi/b.
: now just look at the graph and figure out what those values are.
Thanks, T.Gracken. That really helped. :-)
