Discussion Overview

The discussion revolves around finding the solution of the expression exp(lambda)*Gamma(0,lambda), particularly in the context of definite integrals from 0 to 100,000. Participants are exploring the meaning of "solution" in this context and whether a closed form solution exists.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant seeks to find the solution of exp(lambda)*Gamma(0,lambda) using definite integrals.
  • Another participant questions the meaning of "solution" in relation to a function, suggesting a need for clarification.
  • A further post requests clarification on whether a closed form solution can be obtained, indicating uncertainty about the integration limits and the nature of the result.
  • Another participant expresses confusion regarding the initial question and requests a more explicit formulation of the equation or integral involved.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the meaning of "solution" or the specifics of the integral, indicating that the discussion remains unresolved.

Contextual Notes

There are limitations in the clarity of the initial question, particularly regarding the definition of "solution" and the explicit formulation of the integral, which may affect the discussion.

I need to find the solution of exp(lambda)*Gamma(0,lambda) for using definite integral from 0 to 1e5. this multiplication of exponential with incomplete gamma function

thanks

Hi !
What is the meaning of "solution" of a function ?
 
answer or anyone result or number which can be obtained through above product. when using some integration limits can be supposed or not.if supposed what is the one result.

in other words can we have any close form solution.
 
Sorry, I cannot understand your question.
If you are looking for the solution of an equation, would you mind write the equation with a sign = in it.
If you are looking for a close form of an integral, would you mind write explicitely the integral, with dx in it (or d? if the variable is not x).
