HP Prime Graphing NW280AAABA IPartReal or iPartList, IPart4.3 returns, IquoremInteger1, Integer2

iPart Returns a real number without its fractional part or a list of real numbers each without its fractional part.

iPart(Real) or iPart(List)

Example:

iPart(4.3) returns 4

iquorem Returns the Euclidean quotient and remainder of two integers.

iquorem(Integer1, Integer2)

Example:

iquorem(63, 23) returns [2, 17]

jacobi_symbol Returns the Jacobi symbol of the given integers.

jacobi_symbol(Integer1, Integer2)

Example:

jacobi_symbol(132,5) gives -1

laplacian Returns the Laplacian of an expression with respect to a vector of variables

laplacian(Expr, Vector)

Example:

laplacian(exp(z)*cos(x*y),[x,y,z]) returns –x^2*cos(x*y)*exp(z)- y^2*cos(x*y)*exp(z)+cos(x*y)*exp(z)

lcoeff Returns the coefficient of the term of highest degree of a polynomial. The polynomial can be expressed in symbolic form or as a list.

lcoeff(Poly) or lcoeff(List) or lcoeff(Vector)

Example:

lcoeff(-2*x^3+x^2+7*x) returns -2

legendre_symbol With a single integer n, returns the Legendre polynomial of degree n. With two integers, returns the Legendre symbol of the second integer, using the Legendre polynomial whose degree is the first integer.

legendre_symbol(Integer1, [Integer2])

Example:

legendre(4) gives 35*x^4/8+-15*x^2/4+3/8 while legendre(4,2) returns 443/8 after simplification
