hey i was just wondring if these were any whizzes with the caculater that could enlighten us of a coupple less well known but useful things you can do wtih the caculator.

The one thing i want to find out is how you can get the caculator to solve an equation over the complex number field.

Thanks:)

cSolve will do that for you, I believe it is the same syntax as normal solve but it includes solutions over C not just R like solve

Could someone write up all the tricks they know? I don't think asking my methods teacher 15 minutes before the SAC how to use the calculator is a good idea...


... and yes, I did that.
