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: . . . Aug 14, 2016 ... 3cosx = - sinx cosx = -1/3sinx cosx/sinx = -1/3 sinx/cosx = -3 tanx = -3 x =arctan(-3) = -71.565 degrees The period of the sin(x) sin ( x ) function is 2π 2 π so values will repeat every 2π 2 π radians in both directions.
