Sketch the graph of the ellipse \(\ds \frac{x^2}{9}+\frac{y^2}{16}=1\) and determine its foci. Let \(C\) be the conic which consists of all points \(P=(x,y)\) such ...

Two axes of motion are used by a conventional single point diamond turning (SPDT) lathe to describe a curve in space. The curve is formed between the centerline of the work piece to be machined and ...

Non-rotationally symmetric surfaces are produced by the ability to servo a tool in a coordinated manner, with a workpiece rotating on a two-axis lathe. The diamond machining of far off-axis segments ...

Description: Vectors, integral calculus of functions of a single variable, sequences and series, parametric equations and calculus, conics, and polar coordinates, with applications. MA 169 covers the ...

IN our last notice of this work (vol. xxxi. p. 100) we gave an account of Sections X., XI., and XII. The complete volume contains two additional sections. The first of these treats of plane ...
