Likelihood[dist, {x_1, x_2, ...}] gives the likelihood function for observations x_1, x_2, ... from the distribution dist.
LogIntegral[z] is the logarithmic integral function li(z).
NullSpace[m] gives a list of vectors that forms a basis for the null space of the matrix m.
Precision[x] gives the effective number of digits of precision in the number x.
Unequal
(Built-in Mathematica Symbol) lhs != rhs or lhs != rhs returns False if lhs and rhs are identical.
WeierstrassPPrime[u, {g_2, g_3}] gives the derivative of the Weierstrass elliptic function \[WeierstrassP](u; g_2, g_3).
The solutions to many second-order ODEs can be expressed in terms of special functions. Solutions to certain higher-order ODEs can also be expressed using AiryAi, BesselJ, ...
Pure functions. When you use functional operations such as Nest and Map, you always have to specify a function to apply. In all the examples above, we have used the "name" of ...
The Mathematica function NIntegrate is a general numerical integrator. It can handle a wide range of one-dimensional and multidimensional integrals. Finding a numerical ...
