WebEquation (1) can be reduced to several important cases. For example, if we put λ = 0, f ( u) = 0 or u then we obtain the time FWE without or with damping [ 8, 9, 10 ]. If we set f ( u) = u and β = α /2, then we can have the fractional telegraph equation [ 11, 12, 13, 14 ]. WebThe circumference of a circle = π times its diameter. The diameter is 2 times the radius, so C = 2πR. Now when the radius equals 1, C = 2π. The meaning of this is that any angle can be expressed in radians as an arclength on a circle of radius 1. 2π radians = 360 degrees.
