FP3.1.2 - Inverse hyperbolic functions

Understand inverse hyperbolic functions, their graphs, properties and logarithmic forms, including arsinh x = ln(x + √(1 + x²)).

Use fp3.1.2 - inverse hyperbolic functions to connect the rule to the data and decision in the question.

This matters because fp3.1.2 - inverse hyperbolic functions determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply fp3.1.2 - inverse hyperbolic functions to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: FP3.1.2 - Inverse hyperbolic functions is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
