I have always avoided buying big exspensive caculators with all the bells and whistle on them becuase I do not know what many of the are for in the first place. I know currently have a what I believe to be an overpriced plastic case called the BA II plus by Texas instruments.... My problem is I do not know what all the buttons are for and how to activate them.... and even bigger problem is that the caculator automically rounds my numbers off to the hundreth place.


Can i control this feature?
How do I turn it off/ set it to what I what want.
I need the caculator to give me all digit caculated for doing significant figures.

any advice would be great.

Again! sequences n limits?
x_1 and y_1 are given, x_1>y_1>0

x_n+1 = (x_n+y_n)/2
y_n+1 = sqrt(x_n*y_n)

a)proof y_n< y_n+1
b)proof y_1 < x_n+1 < x_n

c)proof 0<(x_n+1) - (y_n+1)< (x_1 - y_1)2^n

d)explain why {x_n} and {y_n} are convergent and have the same limit


anything will help
Thank you all of u guys

What if you were running really fast towards a car speeding straight towards you and, at the last minute, you tried to jump over it and land on the ground behind? Is this possible? Would you land unharmed? How about a basketball player?? Just a thought...

Could there be, a black hole, created from a star millions of solar masses. This black whole would be near another star of equal mass, after time a second black hole that would meet up with the first. Could the gravational force of such a meeting pull in more and more black holes and nutron stars to the point where the universe would colapse on those. Thus a big crunch, but not from the mass of the universe being large enough?
