DESCRIPTION
What are we Studying?. The “Zoo” of Vector Analysis. A set of outputs (range!). A set of inputs (domain!). A “rule” that takes any input and yields an output. Functions---The Big Picture. Our “zoo”. Calculus C---concentrates (with some exceptions) on Vector Analysis studies - PowerPoint PPT PresentationTRANSCRIPT
