2D probability integral question

Click For Summary
SUMMARY

The discussion centers on understanding the graphical representation of a 2D probability integral, specifically how to interpret the inequalities x1x2 < t and x1x2 > t in relation to the graph of the function. Participants express confusion regarding the derivation of integrals from the graph and the identification of regions defined by these inequalities. The solution involves analyzing the total interval of the function and recognizing the geometric implications of the inequalities on the graph.

PREREQUISITES
  • Understanding of 2D probability integrals
  • Familiarity with graphical representations of functions
  • Knowledge of inequalities in mathematical contexts

the question and solution
after i they find the total interval of the total function
i can't understand
what they do with the graph and how they derive the integrals from it
?
