Homework Statement
find ∫∫ sin(x+y) dxdy in the domain D where D=(x,y) where y≥√x and y≤2x and y≥(1/x) and y≤2/x
Homework Equations
i
The Attempt at a Solution
took y as variable so i have two domains D1 where x is between 0.5 and 1 and y between 1/x and √x
D2 where x is between 1 and 4 power 1/3 and y is between 2x and 2/x
i will reach to one variable in terms of x but it is very hard to find them cos(x+√x) cos(3x) cos(1/x +x) so?
