"imaginary(sqrt(x))" doesn't work properly at x<0. When I tap the function generated by "Curve((gamma(θ); θ), θ, 0, 2π)", my phone shuts down.
Are those 2 separate problems? Please say which version of the GeoGebra App and which phone you have.
for sqrt(x) you can adapt this I think: https://www.geogebra.org/m/xzrf9ubh
Yes, these are two separate problems. The app is called "CAS Calculator" and the version is 5.0.529.0
But could you fix the issues, please?
Also, the link you shared provides an incorrect imaginary part of arcsin(x). If x>1, then Im(arcsin(x))<0, not Im(arcsin(x))>0. For example, Im(arcsin(2))=–ln(2+√3).
Please try the newer version of CAS Calculator (v533)
In v533, the bug with imaginary(sqrt(x)) persists.
Is that better now?
I can't reproduce the crash - please can you share a screenshot just beforehand?
It seems that the crash has been fixed. However, "imaginary(sqrt(x))" is still horribly wrong at x<0.
Please explain what you think it should be
