The video tutorial explains how to determine possible equations for a given graph using the sine function. It covers identifying the midline, amplitude, period, phase shift, and vertical shift. The tutorial provides step-by-step instructions to calculate the values of a, b, c, and d in the equation y = a sin(bx + c) + d. Two possible equations are derived: one with a reflection across the midline and another without. The tutorial emphasizes understanding the graph's features and applying mathematical concepts to derive accurate equations.

What is the general form of a sine function equation used to determine the graph?

• y = a * cos(bx + c) + d

• y = a * tan(bx + c) + d

• y = a * cot(bx + c) + d

• y = a * sin(bx + c) + d
