## What are asymptotic lines?

An asymptotic line is a kind of boundary between positive and negative curvature on a surface. For example, consider a ruled hyperboloid: The red plane intersects it in a circle, a curve which has positive curvature, while the blue plane intersects it in a hyperbola, which has negative curvature.

**What is the equation for an asymptotic curve?**

For a regular surface s, an asymptotic curve is a curve c(t) for which the normal curvature vanishes in the direction c'(t). The differential equation for the asymptotic curves on a surface is e u’ + 2f u’v’ +g v’=0 where e, f and g are coefficients of the second fundamental form.

### What is asymptotic response?

The Standard Asymptotic response is a common finding with rainfall-runoff analysis with the Curve Number method. Converting back to dimensioned rainfall and E(Q), resulting CNs generate the standard asymptotic phenomenon. The effects are most prominent for smaller storms, in the range of P/S< ∼0.5.

**How do you find asymptotic lines?**

An asymptotic line is given by the differential equation: II =Ldu2+2Mdudv+Ndv2=0, where II is the second fundamental form of the surface.

## What’s the meaning of asymptotic?

‘Generally, asymptotic means approaching but never connecting with a line or curve. ‘The term asymptotic means approaching a value or curve arbitrarily closely (i.e., as some sort of limit is taken). A line or curve that is asymptoticto given curve is called the asymptote of . ‘

**Why it is called asymptotic notation?**

The word asymptotic stems from a Greek root meaning “not falling together”. When ancient Greek mathematicians studied conic sections, they considered hyperbolas like the graph of y=√1+x2 which has the lines y=x and y=−x as “asymptotes”. The curve approaches but never quite touches these asymptotes, when x→∞.

### What are different types of curves?

Rational curves

- Circle. Unit circle.
- Ellipse.
- Parabola.
- Hyperbola. Unit hyperbola.

**Why is normal distribution asymptotic?**

“Asymptotic” refers to how an estimator behaves as the sample size gets larger (i.e. tends to infinity). “Normality” refers to the normal distribution, so an estimator that is asymptotically normal will have an approximately normal distribution as the sample size gets infinitely large.
