Hello, this is my first time actually asking in stackexchange. I am a computer engineering student and currently i am doing a linear system course (i don't really know how this is equivalent in engineering course labeling as my major is apparently in faculty of computer science but it's related a bit toward signal processing), i hope i wasn't in the wrong category
So I was to find the fourier transformation of the graph in the picture, and i need to plot the graph in matlab as well. I was allowed to look into the table but I couldn't find it hence I used brute force(integrals) to find the $X(\omega)$ of the signal, which i ended up finding but still there's $e^{-\omega.j}$ stuck which confuses me as i believe the plot should be 2 dimensional only (toward x and $\omega$, not toward j). can somebody help finding any faults/things i missed here?
