Unit T. BIG Question #3

• What is this video about?   This video  goes over why a "normal" tangent graph is uphill where as a "normal" cotangent graph proceeds downhill. Besides their differences, I also detail some of the similarities between tangent and cotangent. 

• What does the viewer need to pay special attention to in order to understand the concept? Pay attention to the use of the unit circle ratios of sin(x)/cos(x) for tangent and cos(x)/sin(x) for cotangent. By understanding this, you will see why we have asymptotes where we do. Also understand how asymptotes play into the why "normal" tangent graphs are uphill and "normal" cotangent graphs are downhill.
