Hi,I'm a beginner.
here's the example:
f[x_] := E^(I*x)
Conjugate[f[x]]*f[x]
I'd like get 1,but it give me a complex function coz it regard x as complex.
please help me:how to claim x is real?
by the way,is that necessary to define a letter as a constant.no matter yes or not,how to refer a letter constant to be real or pure imaginary
Thank you!
