Hello people in mapleprimes,
I tried to solve y=x^3 for x, expecting of getting a result of x^(1/3),
through using restart;assume(x::real,y::real);
But, the result was:
Warning, solve may be ignoring assumptions on the input variables.
(1/3) 1 (1/3) 1 (1/2) (1/3)
y , - - y + - I 3 y ,
1 (1/3) 1 (1/2) (1/3)
- - y - - I 3 y
It means that solve couldn't use the assumption of x and y being real.
On the other hand, reading RealDomain package, y^(1/3) is returned properly:
What I want to ask you is
Aren't there ways other than using the RealDomain package, to obtain the solution of y^(1/3)?
I will be very glad if you give me answers.
