I have defined this function:
Then I tried to plot it using this code
It finally plot it, but it takes about 4-5 minutes to do it. There is a way to speed up similar plots, that involve commands as
EDIT: I observed that changing
NIntegrate the plot speed up a lot, but Im not sure how accurate is the numerical integration to trust in the result of the plot.
Anyway I will like to know if there are other approaches to this problem using the symbolic integration. Thank you.
