The video tutorial explains the concept of a circle with center O and angle POQ, denoted as Theta. It discusses the sine function, defined as opposite over hypotenuse, and how to calculate the sine of 2π minus Theta. The tutorial illustrates the reflection of a triangle along the x-axis in the third quadrant, where y-values are negative, and concludes with the final answer choice.
