What is it that makes us so scared of nuclear energy? When we hear the word “nuclear”, we immediately think of death, war, and glowing genitalia’s. Just because something’s nuclear, doesn’t mean that it’s destructive or explosive. Nuclear energy is by...
find the surface area of f(x,y)=\sqrt{x^2+y^2} above the region
R=\{(x,y):0\leq f(x,y) \leq 1\}
well.. here's what the answer should be.. \sqrt{2} \ \theta
1. formula for Surface area:
\int_{R} \int \sqrt{1+f_{x}(x,y)^2+f_{y}(x,y)^2} \ dA
2. next i need to find the region:
so if...
