Factor polynomials on non-CAS TI-Nspire?

[Steve A]

I don't want to sound too confident on this because I am sure there
will be some bugs, but I think I have a pretty workable polynomial
factoring function now as part of the polynomial toolkit.

It is included in the add.tns and the new poly.tns library files that
are now uploaded at the Google Group site.

To use pfactor, either type in a polynomial up to degree 4 as a string
(like

pfactor("2x^3-6x^2+6x-2")

or, even better, first run "pvar" to define your variable "x" (as in
pvar("x"))

and then no need for quotes: pfactor(2x^3-6x^2+6x-2)

Have also added a nice projectile motion function that returns the
trajectory equation as well as a step-by-step solution, with maximum
time, distance and height.

projectile(init_x, init_y, init_velocity, init_angle (in degrees),
gravity (either 9.8 or 32)) So for example,

projectile(0,1.8, 40, 60, 9.8)

Please let me know if and when you strike a bug!
