Proving Inverse Hyperbolic Function

Click For Summary
SUMMARY

The discussion centers on proving the inverse hyperbolic function, specifically the equation Cosh^(-1)(A/x) = (x√(x² + A))/(2A). The user seeks a step-by-step proof but is met with suggestions to manipulate existing identities rather than direct assistance. Key resources mentioned include Wikipedia pages on logarithmic identities and hyperbolic functions, which provide foundational knowledge but do not offer the detailed guidance requested.

PREREQUISITES
  • Understanding of hyperbolic functions, particularly Cosh and its inverse.
  • Familiarity with algebraic manipulation techniques.
  • Basic knowledge of logarithmic identities.
  • Experience with mathematical proofs and problem-solving strategies.
NEXT STEPS
  • Study the properties of inverse hyperbolic functions, focusing on Cosh^(-1).
  • Learn about hyperbolic function identities and their applications in proofs.
  • Explore algebraic manipulation techniques specific to hyperbolic equations.
  • Review step-by-step proof techniques in mathematical literature.
USEFUL FOR

Mathematics students, educators, and anyone interested in advanced algebra and hyperbolic functions will benefit from this discussion.

Can someone please do a step by step proof for this or send me a link to a step by step webpage.

Thank you very much

Cosh^(-1 ) A/x=( x √(X^( 2 )+A ))/2a





my attempt=>
Cosh^(-1 ) = y

A/x = Cosh^(-1 )

A/x = Sechy
A/x= (2/(e^2 + e^-2))

Thank you , but I have looked at both of those websites.

Im having problems with the manipulation
