[TI-M] Re: complex matrixs etc. and also differential equations!!!
expand will do all sorts of things, including making partial fractions. also, if you're ever
getting answers that don't look simplified or something weird like that, try messing around by
expanding them and factoring them or vice versa. sometimes it makes it collapse it more. very
strange.
now, differential equations. does anyone know how to make the 89 solve differential equations
with greater than second derivative? y''', etc. it will take y' and y'', but gives argument
error if you type y'''. is there another format, or does it just not support it at all?
