Let f(x) = √(x^2 + 1) - 1 (taking the positive real square root, as usual). When x = 10^-3, compute f(x), working to 5 significant figures at every stage of the calculation. Show (algebraically) that f(x) =(x^2)/[√(x^2 + 1) +1]. Use this expression for f to compute...

Each of the sides of a square (S) with an area of 16 is bisected and a smaller square (S2) is constructed using the bisected parts as vertices. The same process is carried out on S2 to construct an even smaller square (S3). What's the area of S3? (Draw a diagram, please?)
