How do I get the constant "e" ? - batx27 - 12-24-2023 09:08 AM Hey everyone, I'm learning pre-calc currently, and I've been trying to figure how to use the constant "e", which is valued at around 2.7...... I would use the value itself, but its too long and I get really confused with more numbers. On my Ti 84, there's a button called "e^y", which uses the constant "e". I can't find it on my hp prime G2. I used the regular letter e but that did not work. Is there an "e" on the Hp prime g2?

If you just want e, just use the lowercase e character. In Home use [ALPHA][SHIFT][E]. In CAS, just [ALPHA][E].

CAS side, enter e simply returns e, but CAS knows e = 2.718... CAS> e → e CAS> float(e) → 2.71828182846 CAS> e := 1 → "sto e not allowed!

Perhaps ε already had its current meaning when e was adopted? RE: How do I get the constant "e" ? - batx27 - 12-25-2023 12:54 AM Thank you very much guys. I found it |
