ACT SAT Prep How do the graphs of two trigonometric graphs compare

The video tutorial discusses how to compare the graphs of y = cosine(θ) and y = 2cosine(θ). It explains the concept of graph transformations, focusing on amplitude and period changes. The teacher uses familiar algebraic functions to illustrate these transformations, emphasizing the effects of multiplying by a constant. The tutorial concludes by highlighting that multiplying the cosine function by 2 affects the amplitude but not the period.
