This question is pretty old, but based on its number of views, it probably deserves a more robust answer. In order to show that this limit exists, we must show that the left-handed limit is equal to the right-handed limit. With the identity ea+b = eaeb and the series defining ex, we can compute the Gateaux derivative d h(eu) = lim e!0 eueeh eu e = eu lim e!0 eeh 1 e = heu. 1.2.3 The absolute value function in R Let f(x) = jxj. Calculation of the limit gives d h f = (h x jxj x 6= 0 jhj x = 0.Jan 1, 2018 ... Show that y = abs(x) is not differentiable at x = 0. (An example of how continuity does not imply differentiability) Need some math help?

I know this is probably to do with the absolute value. Is the absolute value marking necessary because #1 was the antiderivative of a squared variable expression that could be either positive or negative (and had to be positive because, well, natural log) and the second was positive by default?Apr 11, 2019 · About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright ... Examples for. Derivatives. Derivatives measure the rate of change along a curve with respect to a given real or complex variable. Wolfram|Alpha is a great resource for determining the differentiability of a function, as well as calculating the derivatives of trigonometric, logarithmic, exponential, polynomial and many other types of mathematical …The covariant derivative is a generalization of the directional derivative from vector calculus. As with the directional derivative, the covariant derivative is a rule, , which takes as its inputs: (1) a vector, u, defined at a point P, and (2) a vector field v defined in a neighborhood of P. [7] The output is the vector , also at the point P.

The Euclidean norm of a complex number is the absolute value (also called the modulus) of it, if the complex plane is identified with the Euclidean plane. This identification of the complex number x + i y {\displaystyle x+iy} as a vector in the Euclidean plane, makes the quantity x 2 + y 2 {\textstyle {\sqrt {x^{2}+y^{2}}}} (as first suggested by Euler) the …2 days ago · Asset-Backed Security - ABS: An asset-backed security (ABS) is a financial security collateralized by a pool of assets such as loans, leases, credit card debt, royalties or receivables .

Extreme value theorem tells us that a continuous function must obtain absolute minimum and maximum values on a closed interval. These extreme values are obtained, either on a relative extremum point within the interval, or on the endpoints of the interval. Let's find, for example, the absolute extrema of h ( x) = 2 x 3 + 3 x 2 − 12 x over the ...derivatives; absolute-value; Share. Cite. Follow edited Feb 18, 2013 at 21:47.

In summary, the function f (x,y) = sqrt (abs (xy)) is not differentiable at (0,0) as shown by the limit definition of Df (x,y) where the limit along the 45 degree line in the first quadrant is 1, contradicting the existence of a zero map. This also proves that f (x,y) is continuous at 0.
