this is why people hate engineering students...

you choose the major just so you can call yourself an "engineer" before you even graduate, not to mention before even getting a job. engineering is not a fucking science and is really not that difficult. most people that end up majoring in it tend to drop out because they are exceedingly retarded and can't handle a little work. you pussies would drown in a real science or math class where you aren't given your precious "equation sheet" or even numbers.

might as well make it wuick and start taking those history credits. You're gonna need them when you drop out of your major for not being able to pass the weed-out classes.

Must be civil eng, that or you aren't in major classes yet. All the others use dif eq all the time, and it is not that difficult.

To the rest of yous, the only reason you think your shit is harder is because less and less people know and do it. This is why the average person sees math in general as difficult. Also, the higher in math you go the more impractical it becomes.

Props to those mathematicians and physicists who actually want to contribute to bodies of theory currently in circulation.

Unfortunately, that's none of you. Most of you mathematicians want to study an obscure theoretical area that very few people research to begin with. You become a peer review circle jerk and accomplish nothing in the end.

Physicists hold a little more ground...but physics is based in mathematics. Physics is the middleman between theoretical mathematics and applied mathematics like engineering. In the end, though, you're still just a circle jerk of peer reviews.

I'm not saying I do not respect mathematicians and physicists because the ones I have met have actually wanted to contribute something to the current field to better humanity. But I can confidentially say that none of you fall in that category.

So you blatantly admit that you're a waste of government money. Why would I be jealous about that? I have no interest in money and could care less how much I make in the end. At least with engineering I'll be able to solve real world problems.

And you assume I don't understand higher level mathematics and also assume that I have no desire to pursue math past engineering requirements.

On the contrary: I do. I'd love to be a mathematician. But I also do not have resources to support schooling past 4 years. It's sad but that's how it works when neither of your parents have a degree from college.

You're not going to dignify my second question with a response? In other words you agree that calculating that term without the use of variables is insanely fucking idiotic to do. The only logical thing to do is accept that you were wrong in making the asinine statement that mathematics did not require variables to begin with.

>state Euler's identity
>state that mathematics do not need variables based on this
>fail to realize that e is defined by variables
>fail to realize pi shares similar characteristics
>fail to realize the implications of Euler's identity and how it defines basic trig. functions

Give me one plausible scenario that would allow me to switch to pure mathematics based on what I've told you.

Go on: I'll wait.
