Algebra

Simplify Returns an expression simplified.

simplify(Expr)

Example:

simplify(4*atan(1/5)-atan(1/239))yields (1/

4)*pi

Collect Returns a polynomial or list of polynomials factorized over the

field of the coefficients.

collect(Poly

or LstPoly)

Example:

collect(x^2-4) gives (x-2)*(x+2)

Expand Returns an expression expanded.

expand(Expr)

Example:

expand((x+y)*(z+1))gives y*z+x*z+y+x
