It means that "x is an element of every real number", so any numeric value for 'x' would be valid for the equation It is always helpful to use the 'Options' tab and begin a solution with 'a few steps', then increase the number of solution steps when the additional steps are helpful rather than overwhelming and/or confusingFree math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with stepbystep explanations, just like a math tutorX/R ratio are different ways of saying the same thing Please note that as power factor decreases, the X/R ratio increases Right after a fault occurs, the current waveform is no longer a sine wave Instead, it can be represented by the sum of a sine wave and a decaying exponential Figure 3 below illustrates this phenomenon
