gramschmidt Given a basis of a vector subspace, and a function that defines a scalar product on this vector subspace, returns an orthonormal basis for that function.

gramschmidt(Vector, Function)

Example:

⎛

gramschmidt ⎜⎜ 1 1 + x

⎝

1 1 + x – 1

–1 ⎠

green Used in the Symbolic view of the Geometry app. In the definition of a geometric object, including the statement “display=green” specifies that the object defined will be drawn in green.

halftan2hypexp Returns an expression with sine, cosine, and tangent rewritten in terms of half-tangent, and sinh, cosh, and tanh rewritten in terms of the natural exponential.

halftan_hyp2exp(ExprTrig)

Example:

halftan_hyp2exp(sin(x)+sinh(x)) returns

2 ⋅ tan		⎛ x		⎞		exp(x) –	--------1---------
		⎝	2---	⎠
--	2--				+	---------------------2---	exp(x)
-----------⎛---x--⎞-				-----------------
tan⎝ 2--⎠

halt Used in programming to go into step-by-step debugging mode.

hamdist Returns the Hamming distance between two integers.

hamdist(Integer1, Integer2)

Example:

hamdist(0x12,0x38) gives 3

has Returns 1 if a variable is in an expression, and returns 0 otherwise.

has(Expr,Var)

Example:

has(x+y,x) gives 1
