A rectangle is to be inscribed in the ellipse (xb)^2+y^2=1, where b>0 is an unknown real number.

What should the dimensions of the rectangle be (in terms of b) to maximize its area? What is the maximum area (again, in terms of b)?

Consider the IVPs: (A) y'+2y = 1, 0<t<1 , y(0)=2. (B) y' = y(1-y), 0<t<1 , y(0)=1/2. 1. For each one, do the following: a. Find the exact solution y(t) and evaluate it at t=1. b. Apply Euler's method with Δt=1/4 to find Y4 ≈ y(1). Make a table of tn, Yn for n=0,1,2,3,4. c. Find the error at t=1. 2. Euler's method is obtained by approximating y'(tn) by a forward finite difference. Use the backward difference approximation to y'(tn+1)...

Find the equation of the ellipse with foci at (0, 0) and (2, 2), with eccentricity e = 0.5. Express the equation in standard form ax2 + by2 + cxy + dx + ey = f and in terms of the distance formula sqrt(x^2+y^2) + sqrt[(x-2)^2 +(y-2)^2]=? There is an answer posted on Chegg, but I don't think I agree with it. Since the foci are at (0, 0) and (2, 2) it seems that the major axis is rotated...
