## How do you write Weierstrass P?

Typography. The Weierstrass’s elliptic function is usually written with a rather special, lower case script letter ℘. In computing, the letter ℘ is available as \wp in TeX. In Unicode the code point is U+2118 ℘ SCRIPT CAPITAL P (HTML ℘ · ℘, &wp ), with the more correct alias weierstrass elliptic function.

What does ℘ mean?

noun mathematics Any of the Weierstrass elliptic functions .

Is the Weierstrass function even?

The Weierstrass ℘-function is an even elliptic function of order N=2 with a double pole at each lattice point and no other poles.

### What is Weierstrass model?

A Weierstrass equation or Weierstrass model over a field k is a plane curve E of the form y 2 + a 1 x y + a 3 y = x 3 + a 2 x 2 + a 4 x + a 6 , y^2 + a_1xy + a_3y = x^3 + a_2 x^2 + a_4 x + a_6, y2+a1xy+a3y=x3+a2x2+a4x+a6, with a 1 , a 2 , a 3 , a 4 , a 6 ∈ k a_1, a_2, a_3, a_4, a_6 \in k a1,a2,a3,a4,a6∈k.

Can you integrate the Weierstrass function?

The antiderivative of the Weierstrass function is fairly smooth, i.e. not too many sharp changes in slope. This just means that the Weierstrass function doesn’t rapidly change values (except in a few places). integrals, unlike derivatives, are highly insensitive to small changes in the function.

Why is weierstrass function not differentiable?

The higher-order terms create the smaller oscillations. With b carefully chosen as in the theorem, the graph becomes so jagged that there is no reasonable choice for a tangent line at any point; that is, the function is nowhere differentiable.

#### What is reverse A in maths?

Turned A (capital: Ɐ, lowercase: ɐ, math symbol ∀) is a letter and symbol based upon the letter A. The logical symbol ∀, has the same shape as a sans-serif capital turned A. It is used to represent universal quantification in predicate logic, where it is typically read as “for all”.

What does heart struck mean?

1 : struck to the heart. 2 archaic : driven to the heart : infixed in the mind.

Is there a function with no derivative?

In the case of functions of one variable it is a function that does not have a finite derivative. The continuous function f(x)=xsin(1/x) if x≠0 and f(0)=0 is not only non-differentiable at x=0, it has neither left nor right (and neither finite nor infinite) derivatives at that point.

## Can a continuous function be non differentiable?

In particular, any differentiable function must be continuous at every point in its domain. The converse does not hold: a continuous function need not be differentiable. For example, a function with a bend, cusp, or vertical tangent may be continuous, but fails to be differentiable at the location of the anomaly.

What functions are continuous but not differentiable?

In mathematics, the Weierstrass function is an example of a real-valued function that is continuous everywhere but differentiable nowhere. It is an example of a fractal curve. It is named after its discoverer Karl Weierstrass.

What is the name of upside down A?

It was used in the 19th century by Charles Sanders Peirce as a logical symbol for ‘un-American’ (“unamerican”). The logical symbol ∀, has the same shape as a sans-serif capital turned A. It is used to represent universal quantification in predicate logic, where it is typically read as “for all”.

### What was the purpose of weierstrass’preparation theorem?

Weierstrass’ preparation theorem. A theorem obtained and originally formulated by K. Weierstrass in 1860 as a preparation lemma, used in the proofs of the existence and analytic nature of the implicit function of a complex variable defined by an equation f(z, w) = 0 whose left-hand side is a holomorphic function of two complex variables.

Are there any rational functions in the Weierstrass function?

so that all such functions are rational functions in the Weierstrass function and its derivative. One can wrap a single period parallelogram into a torus, or donut-shaped Riemann surface, and regard the elliptic functions associated to a given pair of periods to be functions defined on that Riemann surface.

Is the Weierstrass theorem valid for trigonometric polynomials?

The theorem is also valid for real-valued continuous 2π – periodic functions and trigonometric polynomials, e.g. for real-valued functions which are continuous on a bounded closed domain in an m – dimensional space, or for polynomials in m variables. For generalizations, see Stone–Weierstrass theorem.

#### How is the Weierstrass infinite product theorem generalized?

Weierstrass’ infinite product theorem can be generalized to the case of an arbitrary domain D ⊂ C : Whatever a sequence of points {αk} ⊂ D without limit points in D , there exists a holomorphic function f in D with zeros at the points αk and only at these points.
