Maple solve only positive solutions

WebI have a quadratic equation when I give it to the solver, I get two solutions, one positive one negative. By doing this: solve(eq, x)[0] we can select which one. However, I want to insure that is always positive. I don't want manual stuff! WebThe format in which the Eigenvectors of A are returned is determined by parameter out.By default, an expression sequence is returned as described above. In the case that the output is specified as list, a list of lists is returned.The first element of each sublist is an eigenvalue, the second element is its multiplicity, and the third element is a set of linearly …
