Lim e ^ x-1 x

Jan 26, 2010 · = e^x ( e^-x -1) / e^2x (e^-2x +1) = e^x (e^-x-1) / e^x e^x ( e^-2x+1) = (e^-x -1) / e^x(e^2-x +1) = (e^-x + 1) / (e^-x + e^x) As x approaches infinity, e^-x approaches 0 and e^x approaches infinity. The numerator becomes (0+1) while the denominator becomes (0+infinity) Since the numerator is finite and the denominator is infinite, the limit is 0

If we directly evaluate the limit \\lim_{x\\to 0}\\left(\\frac{e^x-1}{x}\\right) as x tends to 0, we can see that it gives us an indeterminate form. We can solve this limit by applying L'Hôpital's rule, which consists of calculating the derivative of both the numerator and the denominator separately Note that: [math]\displaystyle\lim_{x\to{a}} \frac{f(x)}{g(x)} = \frac{\displaystyle\lim_{x\to{a}} f(x)}{\displaystyle\lim_{x\to{a}} g(x)}[/math] when [math Free limit calculator - solve limits step-by-step This website uses cookies to ensure you get the best experience.

May 9, 2015. It is a remarkable limit, but, if you want to demonstrate it, you have to know the fundamental limit: lim x→∞ (1 + 1 x)x = e (number of Neper), and also this limit: lim x→0 (1 + x)1 x = e that it is easy to demonstrate in this way: let x = 1 t, so when x → 0 than t → ∞ and this limit becomes the first one. So:

As before, we use the exponential and natural log functions to rephrase the problem: 1/x ln x 1 /x ln x x = e = e x . Thus, lim x 1/x ln= lim e x x. Since the function et is continuous, lim e^(1/(x-1/2)), x->1/2. Extended Keyboard; Upload; Examples; Random Solve your math problems using our free math solver with step-by-step solutions.
