SOLVE wrong answers

[jonmoore]

I get the proper answer in CAS of 0.9199... However, as well as following Albert's advice it's worth bearing in mind that you should be using fsolve for that particular problem, as it's a numerical solve problem.

Luckily the Prime gracefully uses Newton's bisection method as a symbolic solve isn't apt for the problem, but it's good to get in the habit of using the apt solve for the job at hand. You can't always be sure that the Prime OS will gracefully fix your error.
