Change the Format of Numbers   (Mathematica How To)
While there is typically one representation for exact numbers, approximate numbers can be presented differently according to the conventions of different professions or ...
TextRecognize   (Built-in Mathematica Symbol)
TextRecognize[image] recognizes text in image and returns it as a string.
Dummy Variables in Mathematics   (Mathematica Tutorial)
When you set up mathematical formulas, you often have to introduce various kinds of local objects or "dummy variables". You can treat such dummy variables using modules and ...

WeierstrassZeta   (Built-in Mathematica Symbol)
WeierstrassZeta[u, {g_2, g_3}] gives the Weierstrass zeta function \[Zeta](u; g_2, g_3).
When you ask for the square root s of a number a, you are effectively asking for the solution to the equation s^2a. This equation, however, in general has two different ...
