Editing Weierstrass theorem

Several theorems are named after [[Karl Weierstrass]]. These include:
*The [[Weierstrass approximation theorem]], of which one well known generalization is the Stone–Weierstrass theorem
*The [[Bolzano–Weierstrass theorem]], which ensures compactness of closed and bounded sets in '''R'''<sup>''n''</sup>
*The Weierstrass [[extreme value theorem]], which states that a continuous function on a closed and bounded set obtains its extreme values
*The [[Weierstrass–Casorati theorem]] describes the behavior of holomorphic functions near essential singularities
*The [[Weierstrass preparation theorem]] describes the behavior of analytic functions near a specified point
*The [[Lindemann–Weierstrass theorem]] concerning the transcendental numbers
*The [[Weierstrass factorization theorem]] asserts that entire functions can be represented by a product involving their zeroes
*The [[Sokhatsky–Weierstrass theorem]] which helps evaluate certain Cauchy-type integrals
