In this lesson, the instructor reviews how to graph y=sin(x+(pi/4)) and determine its period and phase shift. The amplitude is 1, and the period remains the same as the regular sine function, which is 2pi. The phase shift is pi/4 units to the left. The instructor demonstrates two methods for graphing the function, including making a table for x and y. By the end of the lesson, students should have a clear understanding of how to graph sine functions with phase shifts.
