Can someone please help me solve this problem?
Q: The base of S is an elliptical region with boundary curve 9x^2 +4y^2 = 36. Cross-sections perpendicular to the x-axis are isosceles right triangles with hypotenuse in the base.
Can someone please help me solve this? How does the sketch of this even look like?
We are trying to solve volume using cross sections, so V(X) = Integral of A(x) from a to b.
What is A(x) in our case, and a, b?
