Trust me, I did cal 2.

You use subsititution rule to find primitives (hehe, I bet you dont know what a primitive is). When you make a subtitution of the form u(x)=u, you are assuming that u(x) is an invertible function such that there exists some function of the form:

x(u)=x

Now in pure maths, we prove the following:

A function f is invertible on a closed segment if and only if it is one to one on that closed segment. Furthermore, a function is one to one on a closed segment if and only if it is monotone increasing or monotone decreasing on that segment!

Of course, when you do your exams, you just do the substitution blindly because you do not actually have to prove that you can use substitution to find the integral. Its because you are in engineering and everything is simple and "nice". In maths, we get some pretty exotic functions to integrate.

I forgot to mention an important point:

The function is continous on the segment and in this case we also assume it is differentiable on the segment.


My statement is false if we do not assume this.

you´re better off asking this question to compsci, acturalsci students, or perhaps rigorous econ/finance students. At least they learn proofs.

Let me congratulate you on your discussions with the engineering student. Your point was made clear and effectively. I agree with you that engineers should not be high and mighty about their limited knowledge about math and their skills are not any higher than students in other applied sciences. It is expected that the math they learn is just enough to suit their puposes. Could we discuss other things than calculus? I much rather integrate with girls. Classes are about to start and I the parties in the next few weeks will be infinite.

engineering math is far beyond compsci, acturalsci students, and especially econ/finance math

Hey look at me im a dopey math major,

When i calculate the area of a circle, Its all radom ass blind calculations because i didnt take 3 pages to prove that pi=3.14...

why the fuck would anyone who isnt in pure math want to prove that you can sub in a number, NO other major gives a shit about mathematical proofs except math students.

A proof is a proof. What kind of a proof? It´s a proof. A proof is a proof. And when you have a good proof, it´s because it´s proven.

WE dont learn proofs? WTF is linear algebra? Dumbass. A butload of the shit we learn in Engineering is not even used in practice, why the hell should we learn even more esoteric garbage that has absolutley no palpable application? No we leave that stuff to you. Go ahead and become an actuary and have fun comg up with numbers(statitistics) for insurance companies for the rest of your life.

Do not bash actuaries, there are only 10,850 fully certified actuaries in the US and 2,000 in Canada (see www.soa.org). Fully certified actuaries make more money than engineers can dream of. The profession has been ranked one of the 25 best professions in job growth, salary potential, education level, and room for innovation.

BTW, you don´t see engineering on the list!

actuaries and engineers make similar salaries. and it´s a lot more than that McJob your arts degree will give you.

do they even have an actuary program in ontario???? i doubt it.. once it becomes a little more mainstream i doubt they will make engineering money

ACTUALLY, i do see engineers on the list. Software engineering & envirnmental engineering... oh and just to rub it in your face a little more.. few of those were actually professions. There was a pile of titals like Financial Manager this and chief manager that. Why dont you go take "chief financial manager" in university hotshot.
