Example:
isosceles_triangle(GA,GB,angle(GC,GA,GB)
defines an isosceles triangle such that one of the two
sides of equal length is AB, and the angle between the
two sides of equal length has a measure equal to that of
angle ACB.
jacobi_symbol Returns the Jacobi symbol of the given integers.
jacobi_symbol(Intg,Intg)
Example:
jacobi_symbol(132,5) gives -1
KILL Used in programming to stop a step-by-step execution with
debugging.
laplacian Returns the Laplacian of an expression with respect to a list of
variables.
laplacian(Expr,LstVar)
Example:
laplacian(exp(z)*cos(x*y),[x,y,z]) gives -
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||Lst)
Example:
lcoeff(-2*x^3+x^2+7*x) gives -2
legendre_symbol Returns the Legendre symbol of the given integers.
legendre_symbol(Intg,Intg)
Example:
legendre(4) gives 35*x^4/8+-15*x^2/4+3/8
length Returns the length of a list, string or sequence.
length(Lst or Str or Seq)
Example:
length([1,2,3]) gives 3
