Question on doing simple integral and using calculator

SparkyBill said:

I can't get this answer in my calculator and I'm embarrassed but apparently I can't figure out how to do this integral either. I don't see how its simply the time multiplied to the current. 

I don't know why the current wouldn't be squared and divided by 2 when taking the integral.

I just want to point that I've taken the power PE 7 times and never once did I integrate

The fact that this reference handbook is only like 90 pages, and 10 are dedicated to math, I seen them incorporating questions that involve math if applicable like this. I pray I'm wrong because I earned my way through enough with the FE and math I don't want to live that life again. LOL

I have to say, there is a good amount of formulas in the NCEES reference handbook that I've never had to use in any of the practice exams I've taken so far. The majority of them are lightning-protection, for example.

...that kinda worries me, actually. Seeing a lot of formulas in the reference handbook which I've never had to use at all. If they pop up in the actual exam and I have no familiarity with these formulas, I guess I'm going to have to rely purely on this handbook for those questions...

And then there are many formulas I've used in the practice exams I have that aren't in the reference handbook...
