prove that by ( , ) definition
Are well known the trigonometric inequalities...
, (1)
Now deviding each term of (1) by You obtain...
(2)
... and because the first and third term of (2) tends to if , then is...
(3)
With similar procedure You can demonstrate that the same hold for ...
Kind regards
thank you, but i am trying to prove this limit using epsilon delta definition. the information that you gave me is very helpful if i was trying to prove this limit using the squeezing theorem for example.
in delta epsilon definition, basically we are trying to write the expression as where k is a number.
