I have been out of school for awhile need to refresh my math skill. Whats the expected level of math skills for the PE

[VTEnviro]

Some of that will be dependent on which exam you take...

Definitely be sharp on your algebra, geomertry, and trig.

[navyasw02]

Mostly algebra. You wont need to derive anything or do PDEs.

[snickerd3]

you are only allowed a scientific calculator, so if it is more difficult than that you are pretty safe it is not test worthy.

I think the math required to do this problems is all you should worry about, not specific math equations. If you can do your practice problems; you can do the math req'd to pass the PE.

YMMV.

Dont EE's use j instead of i?

Dont EE's use j instead of i?

In general I'd say you are correct, but we can use both, depending on what the subject is. Generally, if you are in a subject area (like power) where you are likely to see i used a lot for current, you will use j for the imaginary number. But if you are doing work in other areas, it may not be as important. There can also be confusion because J can mean current density, although I think they generlly use capital J for that.

So it depends on the context to figure out what it means.

But I guess you are correct, in which case dustin's avatar would mean "old school-" or "not current".

I'm reavealing my nerdyness here... but I've used that on other boards, and only EEs would get it if I used j. This way we all can share in the fun.

But if a null set contains i, then how is it a null set?

Wishful thinking?
