Fourier transformation: why complex integralresults
Answered
Hello!
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?
 \mathbf{b(n) \, := \, \frac{6 \; ί \; \operatorname{sin} \left( n \; \pi \right)  6 \; \operatorname{cos} \left( n \; \pi \right)}{n \; \pi}}
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 5.0.311.03D on LM 18.
Thanks in advance!
Thomas

Hi Thomas,
I don't understand exactly what you need. Do you want b(n) to be displayed as a number?
Anyway, I made this worksheet hoping it is useful. See file attached and check the script in the Setup button.
Cheers!
