Link to the biographies of John Von Neumann, Grace Hopper, Alan Turing, Edsger Dykstra and Donald Knuth

Notes for Homework #12, due Tues. Apr. 30 NOT ACCEPTED LATE

Notes for converting polar to Cartesian and vice versa

Note for plotting polar coordinate functions

The website Wolfram Alpha is a good resource for plotting. For example, use the instruction

plot r = cos(theta)

To see an accurate picture of a circle with its center at (= ½, 0) and radius = ½, passing through both (0, 0) and (1, 0)

Note: The x-axis is all points of the form (x, 0) in Cartesian coordinates. The form looks exactly the same in Polar coordinates, since the angle 0 is the x-axis.

Notes for Homework #11, due Tues., April 23
