What is the correct way to add more than one assumption while integrating?
I am attempting to evaluate the following integral and Mathematica is just stalling, so I'm wondering if my assumptions are the problem:
Integrate[k Sqrt[k^2 - k0^2] ((kf^2 - k^2)/k^2 Log[(kf + k)/(kf - k)]
+ 2 kf), {k, k0, Sqrt[kf^2 + k0^2] - e}, Assumptions -> {Reals, e > 0}]
Reals
in the Assumptions? That all variables appearing in the integrand are real? or that onlye
is real? $\endgroup$ – QuantumDot May 11 '16 at 2:11Assumptions -> {k0, kf, ky} \[Element] Reals && e > 0
