WebNov 20, 2011 · Cheap, non-rigorous, non-mathematical, engineering-type answer: sgn(x) ("signum x", the sign of x, being -1 for x<0 and +1 for x>0).Note that sgn(0) = 0, which is a practical compromise, being the average of -1 ("coming from the negatives") and +1 ("coming from the positives").. Of course we all know that d x /dx is not defined at … Web"The derivative of x 2 equals 2x" or simply "d dx of x 2 equals 2x" So what does ddx x 2 = 2x mean? It means that, for the function x 2, the slope or "rate of change" at any point is 2x. So when x=2 the slope is 2x = 4, as shown here: …

WebDec 28, 2024 · Example 12.6.2: Finding directions of maximal and minimal increase. Let f(x, y) = sinxcosy and let P = (π / 3, π / 3). Find the directions of maximal/minimal increase, and find a direction where the instantaneous rate of z change is 0. Solution. We begin by finding the gradient. fx = cosxcosy and fy = − sinxsiny, thus.
