2018-11-15 18:15:10 +0200 commented answer solve() is not giving the right solutions I figured that it would cancel each other, but i wasnt aware of the simplify-method. Thank you, im going to try this! :) e: im still wondering if it should be this way. If i test this with "in RR" i get false which is not true as u said yourself... thats kinda odd 2018-11-15 15:18:40 +0200 received badge ● Editor (source) 2018-11-15 15:17:54 +0200 asked a question solve() is not giving the right solutions Hey there, i need your help on this one. The following sage code is giving me a headache: f(x) = x^3 + x^2 - 0.1 solve(f==0, x) --> [x == -1/2(1/180Isqrt(13)sqrt(3) + 7/540)^(1/3)(Isqrt(3) + 1) - 1/18(-Isqrt(3) + 1)/(1/180Isqrt(13)sqrt(3) + 7/540)^(1/3) - 1/3, x == -1/2(1/180Isqrt(13)sqrt(3) + 7/540)^(1/3)(-Isqrt(3) + 1) - 1/18(Isqrt(3) + 1)/(1/180Isqrt(13)sqrt(3) + 7/540)^(1/3) - 1/3, x == (1/180Isqrt(13)sqrt(3) + 7/540)^(1/3) + 1/9/(1/180Isqrt(13)sqrt(3) + 7/540)^(1/3) - 1/3] So i'm getting these 3 solutions, but they are not in R (real numbers), which they should be. Im figuring there is some problem with really long terms or something? Is there an easy solution for this? Is the solve()-method here working as intended?

So the bottom line for this kind of problem is: Do all the logic in python right? :) 2018-07-31 17:23:50 +0200 answered a question Is there a way to use sage-boolean-values in Latex Thanks for your answer.

I want to create randomized mathproblems and i want latex to decide what to print depending on calculations in sage. So here is a functional minimal example: \documentclass{article} \usepackage{sagetex} \begin{document} \begin{sagesilent} a = ZZ.random_element(1,20) b = ZZ.random_element(1,20) \end{sagesilent} $\sage{a}-\sage{b}$ \end{document}  What do i need to do if i want to switch a and b depending on if the result is negative or not?
