Calculus
Section 2.4

I don't need to know this stuff to succeed in Calculus. However, I would like to have your math work reply file away as future study notes and/or reference notes. How about working out 26?

26.
Given any number ε>0 choose δ such that: δ < ε^(1/3)

Then, for x element (−δ,δ) we have that: |x| < δ

|x^3|=|x|^3< δ <(ε^(1/3))^3= ε

or shortly:

x element (−δ,δ) =>|x^3|=ε

Thank you but I wish that you would break down each step with words explaining what you are doing.
Please check out my Jenn notes in your PM inbox.

See below. I sent my 3rd or 4th message to Jenn's website today. They promise to contact within 24 hours. No one ever replies.

I think no one will ever reply. It seems to me she has that site just to make easy money.

Can you contact the site for me? Just click on CONTACT. You don't have to join to send a message. I just want to see if they respond to you. I am disappointed and feel deception coming on like a dark cloud.

Ok. I will NOT renew my membership next year. In fact, I would like to cancel my membership now and get my money back. However, someone needs to reply in order for that to happen. So, I'm stuck with Jenn until next May.
