1.19 Prove: If

s_(n)

for all

n

and if both

s_(n)->L

and

u_(n)->L

then

t_(n)->L

as

n->\\\\infty

as well. (This is sometimes called the squeeze theorem or the sandwich theorem for sequences.)

1.19 rove: If sntnun for all n and if both snL and unL then tnL as n as well. (This is sometimes called the squeeze theorem or the sandwich theorem for sequences.)
