What to Do with Inverse Functions in Complex Cases?

Click For Summary
SUMMARY

The discussion focuses on finding inverse functions for complex cases, specifically addressing hyperbolic functions and split functions. The inverse of the hyperbolic tangent function is defined as x = arctanh(y). For split functions, it is essential to determine the corresponding range of y for each specified range of x. The participants emphasize the importance of understanding the function definitions and their respective domains to accurately compute the inverses.

PREREQUISITES
  • Understanding of hyperbolic functions, specifically hyperbolic tangent.
  • Knowledge of inverse functions, including arcsine and arctangent.
  • Familiarity with piecewise functions and their domains.
  • Basic algebra skills for manipulating equations.
NEXT STEPS
  • Study the properties and applications of hyperbolic functions in calculus.
  • Learn how to derive inverse functions for piecewise-defined functions.
  • Explore the concept of function ranges and how they relate to inverse functions.
  • Practice solving complex inverse function problems using examples from calculus textbooks.
USEFUL FOR

Students and educators in mathematics, particularly those studying calculus and advanced algebra, as well as anyone interested in mastering the concepts of inverse functions and their applications.

i need to find the inverse function of these:

i know that if y=sinx
then its inverse whould be x=arcsin y

but the first case has two = signs
and the second one is a split function

what to do in these cases?

In the first case, you are being given the definition of the hyperbolic tangent. So one answer is x = arctanh y. But presumably you are to ignore this, and solve it as if you were given only the function on the far right.

As for the split function, for each specified range of x, what is the corresponding range of y?
