Homework Help Overview

The discussion revolves around the integration of the expression "e^[-(x/xa)]", where "xa" is a point of confusion regarding its meaning and context. The subject area appears to involve calculus and possibly applications in physics.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants question the interpretation of "xa" and whether it represents a multiplication or a distinct variable. There are suggestions regarding substitution methods and the need for clarity in the problem statement.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the expression and offering various approaches to integration. Some guidance has been provided, but there is no explicit consensus on the correct interpretation or method.

Contextual Notes

One participant mentions that they are studying for a physics test, indicating that this may not be a formal homework assignment. There is also a note about the need for more descriptive titles in future posts.

Does xa mean x*a, or is it a variable different from x?
 


Errr... Do you mean [itex]e^{\frac{x}{xa}}[/itex] ? If so just cancel the x. You also need to show some working out and should have a more discriptive title. We are here to help not to do homework.
 


On the other hand if you mean xa, some fixed (constant) value, then use the substitution u= x/xa.
 


i meant x subscript a. but i figured out the answer. and fyi this is not my homework. I am studying for my physics test. but thanks for being rude...
