Learning the basics to graph the cosine function with its points

The video tutorial revisits basic graphing concepts, starting with the equation y = X + 1, and progresses to understanding functions and their properties. It introduces the concept of input and output in functions, using function notation. The tutorial then explores the cosine function through the unit circle, explaining how to determine output values for given angles. Finally, it demonstrates how to graph the cosine function, highlighting its periodic nature and the relationship between angles and their corresponding cosine values on the unit circle.

What are the coordinates of the points on the unit circle mentioned in the text?

What pattern is observed in the output values of the cosine function as described in the text?

How does the text explain the cosine of an angle in relation to the unit circle?
