@TECHREPORT{AICPub1480:1971, AUTHOR={Munson, John H.}, TITLE={Efficient Calculations on Points and Lines in the Euclidean Plane}, ADDRESS={333 Ravenswood Ave, Menlo Park, CA 94025}, INSTITUTION={AI Center, SRI International}, MONTH={Oct}, NUMBER={61}, YEAR={1971}, KEYWORDS={Trigonometry, Euclidean Spaces, Points and Lines, Calculations}, ABSTRACT={Calculations involving points and lines in Euclidean spaces are often subject to annoying anomalies when the trigonometric functions are invoked. This paper illustrates a method by which use of these functions may often be avoided, and presents explicit formulas for four basic calculations involving points and lines in two dimensions.} }
