Solving a complex equation involving conjugates with Mathematica

In summary, the conversation discusses the issue of obtaining solutions for equations involving conjugates in Mathematica. The speaker mentions attempting to use the Solve function, but encountering errors such as "InverseFunction" and "tdep". They suggest using the Reduce function as an alternative when Solve fails. The speaker also mentions their interest in solving more complex equations that cannot be solved by hand in a reasonable amount of time.

How can one obtain (using Mathematica) all the solutions of an equation involving conjugates like for example [tex]z \bar{z}=1[/tex]. Although this equation is very simple, it seems that Mathematica is not able to handle it. I obtain:
Code:
Solve[z Conjugate[z] == 1, z]
InverseFunction::ifun: Inverse functions are being used. Values may be lost for multivalued inverses. >>
Solve::tdep: The equations appear to involve the variables to be solved for in an essentially non-algebraic way. >>
Solve[z z^\[Conjugate]\[LongEqual]1,z]
Of course I'm not interested in this particularly simple equation, but of an equation involving many terms, which can't be, unfortunately, done by hand in a reasonable amount of time.
Any ideas?

When Solve fails, especially with the non-algebraic error, I usually use Reduce.
 

FAQ: Solving a complex equation involving conjugates with Mathematica

1. What is a conjugate in mathematics?

A conjugate in mathematics refers to a pair of complex numbers that have the same real part but opposite imaginary parts. In other words, if a complex number is written in the form a + bi, its conjugate would be a - bi.

2. How can Mathematica be used to solve equations involving conjugates?

Mathematica has built-in functions, such as Conjugate and Simplify, that can be used to manipulate and solve equations involving conjugates. These functions allow for easy manipulation of complex numbers and their conjugates, making it a powerful tool for solving complex equations.

3. Can Mathematica handle equations with multiple conjugates?

Yes, Mathematica can handle equations with multiple conjugates. It has the ability to simplify and manipulate expressions with multiple conjugates, making it a useful tool for solving complex equations.

4. Are there any limitations to using Mathematica for solving equations involving conjugates?

While Mathematica is a powerful tool for solving equations involving conjugates, it does have some limitations. It may struggle with complex equations that involve a large number of variables or have multiple solutions.

5. Are there any tips for using Mathematica to solve equations with conjugates?

One tip for using Mathematica to solve equations with conjugates is to use the Conjugate function to simplify expressions before solving the equation. It is also helpful to use the Simplify function to simplify the equation as much as possible before attempting to solve it.
