 In this video, we provide the solution to question number five for practice exam number two for math 1060, in which case we're asked to find all values of x in the domain zero to two pi. Notice that zero is included, but two pi is not. Sorry, two pi. We want to find all values x for which sine of x is equal to zero. So if we think of the standard graph of sine without any transformations whatsoever, the graph looks something like this, for which the x intercepts would be here at zero, here at pi, and then here at two pi. But again, we go up to two pi but not including two pi. So there's going to be two places where sine is equal to zero that happens at zero and pi. So the correct answer would be B.
