## Multiplication & coefficients

Hi, here is the problem I need help with. It's due by Fri 10/7.
Multiply (1- 1/2t^2 - 1/8t^4 - 1/6t^6 - 5/128t^8 - 7/256t^10) by itself and verify that the coefficients of t^4,t^6,t^8, and t^10 are each zero. If you have MATHEMATICA (which I don't) use the EXPAND comand to simplify the computations.

I do have Maple 7 & cannot figure out how to do this on Maple. If someone can even give me the steps on Maple 7, I would be greatful. Thanks.
