## Question

The coefficients of a "Randomized" polynomials are too big for my purposes

Use R ::= Q[x,y,z]; Randomized(x-yz); 2129104241yz - 2703411994x -------------------------------

What can I do?

## Answer

This function will produce a randomized polynomial with "small" random coefficients

Define MyRandomized(F, Range) Return Sum([ Rand(-Range,Range)*T | T In Support(F)]); EndDefine;

MyRandomized(x-yz, 4); 2yz + 6x -------------------------------
