Graphs of Trig Functions > Finding amplitude and midline of sinusoidal functions from their formulas
The video for this lesson could be improved. It approaches, but doesn't quite cover: f(x)=asin(bx+c)+d. Then the practice questions are written as if it DID cover it completely. Perhaps the video should open with that equation and do a full breakdown of the variables and transformations.
