HP Prime Graphing NW280AAABA manual Sylvester Returns the Sylvester matrix of two polynomials

sylvester Returns the Sylvester matrix of two polynomials.

sylvester(Poly1, Poly2, Var)

Example:

	1 0	–1	0	0
sylvester(x2-1,x3-1,x) gives	0 1	0	–1 0
	0 0 1		0	–1
	1 0	0	–1 0
	0 1	0	0	–1

table Defines an array where the indexes are strings or real numbers.

table(SeqEqual(index_name=element_value))

tail Given a list, string, or sequence of objects, returns a vector with the first element deleted.

tail(List) or tail(Vector) or tail(String) or tail(Obj1, Obj2,…)

Example:

tail([3 2 4 1 0]) gives [2 4 1 0]

tan2cossin2 Returns an expression with tan(x) rewritten as (1–cos(2*x))/ sin(2*x).

tan2cossin2(Expr)

Example:

tan2cossin2(tan(x)) gives (1-cos(2*x))/sin(2*x)

tan2sincos2 Returns an expression with tan(x) rewritten as sin(2*x)/ (1+cos(2*x)).

tan2sincos2(Expr)

Example:

tan2sincos2(tan(x)) gives sin(2*x)/(1+cos(2*x)

transpose Returns a matrix transposed (without conjugation).

transpose(Matrix)

Example:

transpose ⎛⎜ 1 2 ⎞⎟ returns ⎝ 3 4 ⎠
