There are a number of functions built into Mathematica which, like Plot, have various options you can set. Mathematica provides some general mechanisms for handling such ...

This constructs the sum ∑_(i=1)^7 (x^i)/(i) . You can leave out the lower limit if it is equal to 1. This makes i increase in steps of 2, so that only odd-numbered values are ...

You can think of an expression like f[x] as being formed by applying an operator f to the expression x. You can think of an expression like f[g[x]] as the result of composing ...

ParallelTable[expr, {i_max}] generates in parallel a list of i_max copies of expr.ParallelTable[expr, {i, i_max}] generates in parallel a list of the values of expr when i ...

NInverseFourierCoefficient[expr, n, t] gives a numerical approximation to the function, evaluated at t, whose Fourier exponential series representation has coefficients given ...

NorlundB[n, a] gives Nørlund polynomials B_n^(a) of degree n in a.NorlundB[n, a, x] gives generalized Bernoulli polynomials B_n^(a)(x).

Sin[z] gives the sine of z.

AiryAi[z] gives the Airy function Ai(z).

AiryBi[z] gives the Airy function Bi(z).

ArcCos[z] gives the arc cosine cos -1 (z) of the complex number z.
