From there, you have two options: 1. Graph it, and you'll be able to see just how many solutions this equation has. Oct 5, 2004 ... ( sinx, 0 < x ≤ π,. 0,. −π ≤ x < 0. (b) Find its Fourier series. (c) Graph the first 5 Fourier sums and compare with the function. Start with a = 0. For x ∈ (0, 2π), f0(x) = sinx = 0 ⇐⇒ x = π so Ψ(0) = {π}. Notice that for x near π, for example in the neighborhood (π/2, 3π/2), and for a ... Oct 18, 2006 ... a) What is the domain of f? Since you can't take the square root of a negative number, I set 1 - sinx > 0: . . . Apr 12, 2018 ... Sin(x) is positive in first two quadrants. (From 0 to π ). In the given interval x € (0,π) so that sin(x) is positive. ... sinx + a = 0 that is, the x ∈ (0,2π) such that sinx = −a. Let Ψ : A → 2 ... f0(x) = sinx = 0 ⇐⇒ x = π so Ψ(0) = {π}.
