Brett explains graph transformations including amplitude & period change, reflections, and vertical & horizontal shifts (phase shift) as they apply to trigonometric functions. Skip to 14:20 for an example of a Tangent graph with an amplitude change and reflection, skip to 21:30 for an example of a Cosine graph with a period change and vertical shift, and lastly skip to 31:51 for an example of a Sine graph with both a horizontal and vertical shift and period change.
