Sometimes I have very long and complicated equations, when I evaulate the equations for example taking derivative or integral there will be several conditions with the answer. My question is that; is there any way that I enter the conditions at the begining of the program so that so that it will not appear in the evaluation result?
I will give a simple example:
pdf = x^(L-1)/( γ^L Gamma[L]) Exp[(-x)/γ];
Re[L] > 0;
Integrate[ pdf, {x, 0, γ}]
ConditionalExpression[ (Gamma[L]-Gamma[L,1])/(Gamma[L]), Re[L] > 0 ]
in the above example even if I write the condition which is Re[L] > 0
, it will appear again at the result of evaluation.
$Assumptions = Re[L] > 0
and appropriately writing your integral. $\endgroup$$Assumptions = Re[L] > 0
you can write all your conditions at the begining of the program like this:$Assumptions = Re[b] > 0 && Re[Sqrt[b]] > 0;
by putting&&
between your conditions. Thanks $\endgroup$
