Graphing Sine and Cosine Functions

The video tutorial covers graphing sine and cosine functions with vertical shifts. It begins with an introduction to vertical shifts, followed by an explanation of amplitude, period, and vertical shift concepts. The tutorial then demonstrates how to graph these functions with vertical shifts through two examples: a sine function and a flipped cosine function. Key points include understanding the midline, amplitude, and the effect of vertical shifts on the range.

What is the main focus of the video tutorial?
