Thanks, I use IJulia I delete it

I delete readline ?
Because plot doesn't dislay
Thanks

Oh now I see... Neat.
But you then need to have different ranges for the x variable.
using Plots
x = linspace(-2, 2, 100)
xh = linspace(0, 2, 50)
xk = linspace(-2, 0, 50)
f =

using Plots
x = linspace(-2, 2, 100)
xh = linspace(0, 2, 50)
xk = linspace(-2, 0, 50)
f = sqrt(complex(4 .- x.^2))
g = -sqrt(complex(4 .- x.^2))
h = sqrt(complex(-xh.^2 .+ 2 * xh))
k = -sqrt(complex(-xk.^2
Thats what I want yin/yang, can't I get rid of the line on zéro ?
Thanks your model works.
using Plots
x=linspace(-2,2,100)
f(x) = sqrt(complex(4.-x.^2))
g(x) = -sqrt(complex(4.-x.^2))
h(x) = sqrt(complex(-x.^2.+2*x))
k(x) = -sqrt(complex(-x.^2.-2*x))
plot([real(f(x)),real(h(x)),
Not exactly sure what you want to do.
But you take the square root of negative numbers, which
then is a complex number. I dont think you can give plot a complex number
to plot?
The following code works, maybe you can work your way from there...
```julia
using Plots
x=linspace(-2,2,100)
f(x) =
Always the same problem f and g works but h and after give this error.
I notice if I change x -4,4 I have got the same error
