Asymptote Definition and 79 Threads

At critical condition, ##\omega=0## so time period will be infinite and so will be ##\lambda##.Therefore, the critical resistance will be the corresponding resistance(plus galvanometer resistance)of the asymptote of ##\lambda## vs. ##R_2## graph(the graph is a rectangular hyperbola). But here's...

Given f(x) = [sqrt{2x^2 - x + 10}]/(2x - 3), find the horizontal asymptote. Top degree does not = bottom degree. Top degree is not less than bottom degree. If top degree > bottom degree, the horizontal asymptote DNE. The problem for me is that 2x^2 lies within the radical. I can rewrite...

I'll write my procedure: $$\lim_{x\to\infty}[\frac{(a-2)x^3+x^2}{ax^2+6x+1}]\rightarrow\frac{x(a-2)}{a}\in \mathbb{R}$$ And now, assumed that everything's correct, how do I assign ##a## a value for having that limit finite and ##\in \mathbb{R}##, and so an horizontal asymptote?

I tried graphing the function in the calculator, and the graph seems to have a horizontal asymptote at y=0, not at y=1. Why is this so? Thanks for helping out.

I know the hyperbola of the form x^2/a^2-y^2/b^2=1 and xy=c; but coming across this question I'm put in a dilemma of how to proceed with calculating anything of it - say eccentricity or latus rectum or transverse axis as said. How to generalize a hyperbola (but i don't want a complex derivation...

Playing with some numerical simulations, I plotted this in Wolfram Cloud / Mathematica: ##x^3-\frac{x^5}{x^2+2}## I had naively expected it to approach ##x^3−x^3=0##, but that isn't the case. It approaches 2x. I can now vaguely understand that the two terms need not cancel at infinity, but I'd...

Hi everyone, I was working on a problem recently, something related to oral absorption of drugs. Cutting a long story short, at some point I needed to calculate the right asymptote of this function: A(t) = Ln(k⋅t) - k⋅t where k,t ∈ℝ+. The derivative of A(t) tends to -k for t→∞, so I thought...

Hello all! I'm new to this forum (and forums in general as this is my first) so please excuse my etiquette. When I was in my trig class (I'm a high schooler), we brushed up upon asymptotes, and it made me wonder: Can time be modeled by an asymptote? I like the idea of a line moving in a...

Hello, i'm having some trouble understanding the definition of an asymptote, or rather the conditions that must be met in order for a line to be one. I have; "Let f : A \longrightarrow B be a function and A \subset R, B \subset R. A straight line is called an asymptote if one of the following...

Hey! I know how to find slant asymptotes of regular rational functions, but what happens when the function is $y= \frac{x}{2} - \tan^{-1}x$ ? Is there a special way to do this? I know what the $\arctan x$ function looks like and that is $y\in(-\frac{\pi}{2},\,\frac{\pi}{2})$ and it is...

Why is the slant asymptote pictured here correct for this function? I was under the impression an asymptote was never crossed by the function. I get that the dividend gives the equation for the asymptote for a non zero remainder, but seeing this graphically is a bit confusing. Thanks! (EDIT...

This is just a general concept question. Why is that an equation with a numerator to a greater degree than the denominator has no asymptote & the opposite does? Also why is the coefficient of the variable to the highest degree the horizontal asymptote? Maybe a proof would help here :P Anyway...

Question: Guess the oblique asymptote of the graph f(x) for x→∞. Write down the limit you have to compute to prove that your guess is correct. f(x)= \sqrt{(x^{4}+1)/(x^{2}-1)} so the limit would be: lim x→∞ \sqrt{(x^{4}+1)/(x^{2}-1)} I sketched out a graph but I just have no clue how to...

Can someone tell me why the expected velocity of the outer most stars of spiral galaxies has an asymptote quite a bit greater than zero? For example NGC 3198 at a radius of 50 kpc appears to be reaching it's asymptote at about 40-50 km/s which seems illogical.
