12, I'm just guessing, found an other invite in the mean time, but I'm curious what the answer is

the latest update should have a Z- dimension, but it's not working

I'm considering sending this to my teacher

I do industrial science, 6th year, but I'm going to learn about integrals in my second trimester.

I know

going to update geogebra, maybe I'm able to solve it there, since mr engineer is till showing off with his high class math.

My calculator has no z-dimension

I was almost certain it was wrong, but I had nothing better

or am I being silly?

the answer is infinite, there's no domain of your function.

I'm not even going to attempt that, you work with 3 dimensional curve.
