Fourier transformation: why complex integral-results
For School, I just wanted to make a fouriertransformation. I just wonder why I get ί in the results. There can't be something complex, does it?
Does someone know, why this happens? (the ί)
It seems that this leads to not be able to view this plot ...
I'm using GeoGebra 5.0.311.0-3D on LM 18.
Thanks in advance!
