HP 41 Polar Plots?
Anyone know if it's possible to plot f(r,theta) using an hp 41 and 82240 printer? For example:
R(theta) = 1/2 + 3/4*sin^2(theta) + 1/2*cos(theta) describes the approximate plastic zone shape (normalized) ahead of a crack tip. Below is the solution in r, theta, x, y from 0< theta < 180 deg. Code:
Ideally, you'd sort the x, y values to get the correct shape. I thought about writing a subroutine to do this using either "regplot" or "stkplot". Note there a two solutions at x = 0. |
