In summary, the conversation discusses the solution for x in the equation ex = 1/x and the difficulty in finding a comprehensible explanation. The Lambert W function and the omega constant are mentioned as potential solutions, but they are considered complex. The conversation also mentions finding beautiful identities despite not fully understanding them.

I am looking for the solution for x of the equation ex = 1/x. I've looked around and the answers seem a bit incomprehensible, is there a more approachable explanation ? I've only done high school math but was pretty good at it. I'm hoping that I'm posting in an appropriate place for this question.

It certainly isn't simple. I'd gotten as far as the Wiki entry before but found it intractable. Even if I don't understand it there are some beautiful identities to be found though. Thanks for the replies.
 

FAQ: Finding an Approachable Solution for x of ex = 1/x

How do you solve for x in the equation ex = 1/x?

To solve for x in this equation, we can use logarithms. Taking the natural logarithm of both sides, we get ln(ex) = ln(1/x). Using the properties of logarithms, this simplifies to x = 1/e.

What does the solution represent in the context of the equation ex = 1/x?

The solution x = 1/e represents the value of x that satisfies the equation, meaning when x is substituted into the equation, it will result in the equation being true. It is the exact value of x where the graph of ex and 1/x intersect.

Are there any other solutions for the equation ex = 1/x?

Yes, there are infinitely many solutions for this equation. In addition to x = 1/e, there are also negative solutions for x. These values can be found using complex numbers, but in the context of real numbers, x = 1/e is the only solution.

Can this equation be solved without using logarithms?

Yes, there are other methods for solving this equation without using logarithms. One method is to graph both ex and 1/x and find the point of intersection. Another method is to use approximations, such as using a calculator or estimating the value of x.

What is the practical application of solving this equation?

This equation has many practical applications in mathematics, physics, and engineering. For example, it can be used to model growth and decay in various systems, such as population growth or radioactive decay. It is also used in calculus to find the slope of a tangent line to a curve at a specific point.
