okay, does it work for polar or elliptic coordinates? > draw(x=1, x, y, range == [-3..3, -3..3])
does give a vertical line. and what if i want θ=1 in polar coordinates? > draw(t=1, t, r, range == [-%pi..%pi, -3..3], coordinates==polar) plots a vertical line again as if the coordinates are still Cartesian. in polar coordinates θ=1 is a line running through the pole atthe angle of elevation of 1 radian. ------- Original Message ------- On Monday, May 1st, 2023 at 11:40 PM, Waldek Hebisch [email protected] wrote: > On Mon, May 01, 2023 at 06:16:26PM +0000, '68th' via FriCAS - computer > algebra system wrote: > >> is it possible in FriCAS to draw an equation and not a function? y=1 or x=1 >> in Cartesian coordinates, for example? > > Yes, but this is limited to algebraic functions.
