RE: Why solve() is not solving?
Yes, this is what i'm executing:
Code:
 Cmd: √(-ω^2*μ*ε*0.00000125664*8.85419e−12+()*ω*μ*σ*0.00000125664)▶gamma(ω,σ,ε,μ) Result: (ω,σ,ε,μ)->√((-ω²)*μ*ε*0.00000125664*8.85419e−12+()*ω*μ*σ*0.00000125664) Cmd: gamma(1,1,1,1)  Result: 7.92666386315e−4+7.92666386322e−4* Cmd: solve(gamma(x,1,1,1) = 7.92666386315e−4+7.92666386322e−4*()) Result: [] Cmd: fsolve(gamma(x,1,1,1) = 7.92666386315e−4+7.92666386322e−4*(), x = 1) Result: 4.88592031168e−9+5.90761930892e−7* As you can see, the result of fsolve is way different from 1. Cmd: √(-(2*π*f)^2*μ*ε*0.00000125664*8.85419e−12+()*2*π*f*μ*σ*0.00000125664)▶gamma(f,σ,ε​,μ) Result: (f,σ,ε,μ)->√((-(2*π*f)²)*μ*ε*0.00000125664*8.85419e−12+()*2*π*f*μ*σ*0.00000125664) Cmd: gamma(1,1,1,1) Result: 1.98691997624e−3+1.98691997635e−3* Cmd: solve(gamma(x,1,1,1)=1.98691997624e−3+1.98691997635e−3*) The emulator crashes after this command. The calc instead solves this. The result is: {0.999999999998+5.53621719455e−11*} Cmd: fsolve((gamma(x,1,1,1)) = (1.98691997624e−3+1.98691997635e−3*()),x = 1) The emulator crashes after this command. The calc instead solves this. The result is: 0.999999999998

(I'm using the character sigma (lower case) σ, that is an alias of the character sigma (upper case) ∑ which is the summation function, as a variable. I don't think this is the problem beacuse i'm using it in both situations...)
