Double Integral Homework R1 & R2

Click For Summary
SUMMARY

The discussion focuses on the evaluation of a double integral with specific limits defined as R1: 0≤y≤x and R2: 0≤x≤√π. The user initially misinterprets the limits, believing that the inner integral should be defined by y=1.5, suggesting that x would equal 1.5 as well. However, the correct interpretation is that R1 serves as the inner integral and R2 as the outer integral, with the limits for x extending to √π, not 1.5.

PREREQUISITES
  • Understanding of double integrals in calculus
  • Familiarity with integral limits and their graphical representation
  • Knowledge of the properties of square roots and their implications in integration

The Attempt at a Solution



The question is in the picture, the new integral I got was

R1:0≤y≤x

R2:0≤x≤1

However the answer is
R1: is inner integral R2: is outer integral

I drew a graph showing my thought process.

R1:0≤y≤x

R2:0≤x≤√∏

The double integral says y goes up to root pi. What does the inner integral look like when y is 1.5, say?
 
Wouldn't X be 1.5 as well, since x=y?
