Graphing the Sine Function with a Reflection Over the Y Axis

The video tutorial explains how to graph y = -sin(x) by reflecting the parent graph of sine over the X-axis. It begins with an introduction to the concept of transformations and the specific changes involved in graphing negative sine. The tutorial then covers the properties of the parent graph of sine, including its amplitude and period, and demonstrates graphing two periods of the sine function. Finally, it shows how to reflect the graph over the X-axis to achieve the graph of y = -sin(x).
