Hello, Ivan
I have used Geogebra only a bit. But I have more experience with Modellus, it can be useful for IBSME both the Maths and in Physics. One can model physical processes inmaqthematical terms.
Best regards!
Peter
I agree with Peter, I have used Modellus a bit and find it quite amazing. I even found many examples n internet which i could use directly.
