Limits by graphs Use a graphing utility to plot y = sin px
Chapter 2, Problem 49(choose chapter or problem)
Limits by graphs Use a graphing utility to plot y = sin px sin qx for at least three different pairs of nonzero constants p and q of your choice. Estimate lim xS0 sin px sin qx in each case. Then use your work to make a conjecture about the value of lim xS0 sin px sin qx for any nonzero values of p and q.
