... vectors is h5/ 2 + 2 cos(−3π/8), 5/ 2 + 2 sin(−3π/8)i ≈ h4.3, 1.69i. Adding the two vectors is easier in this form than in the (m, θ) form, provided that we’re willing to have the answer in this form as well. It is easy to see that scalar multiplication and vector subtraction are also easy to comput ...

... Problem 3. Let g : R2 → R be a differentiable function such that g(x, y) = x − y, and let f : R → R be a differentiable function such that f (R) = R. The composition h = f ◦ g : R2 → R is then a differentiable function and its value at (x, y) is h(x, y) = f (x − y). (a) Suppose that f is monotone an ...
