/sqt/ - Stupid Question Thread

Help me out anons. I'm going to college this fall. Should I choose EE or engineering physics?

EE:

Pros:
+ Taught in English (as I'm from a non-English speaking country.)
+ Smaller class size.
+ Better job prospect after graduating in case I can't get into grad school immediately afterwards.
Cons:
+ Higher tuitions than ENPH (160%)
+ I don't know it EE is what I really want to do with my life.


ENPH:

Pros:
+ A breed of physics and engineering. Jack of all trade. Get to study QM and Electromagnetic Field Theory.
=> Does this really make me a more well-rounded candidate for just any science/engineering grad programs?

Cons:
+ Nobody knows that ENPH exists.
=> Hard to find a job afterwards.
+ Taught in my native language.
+ Class size can be as three times as large.

Can anyone explain what happened in the red box, logically?
I see that they both have the same base, but I don't understand how or why it's okay to drop the base entirely.

Since the base is the same, would it matter if you replaced them with other numbers with the same value?

Took a base 3 logarithm of both sides

The exponential function is injective. This means the two (equivalent) things:

1) x != y implies that a^x != a^y
2) a^x = a^y implies x = y

The reason it is invective is because it is strictly increasing. You should have studied that in high school.

Was it for academic prep or just fun? Props either way.

I would keep practicing the fundamentals periodically, since they undergird so much other math. A good book for fundamentals is the classic Princeton book of mathematics.

>The reason (...) is *that*
Fuck, I'm writing like a illiterate person.

On my Calc 2 quiz yesterday I had to expand (is that the right word?) a maclaurin series for the function 2/(1+x^2). I was running out of time and didn't want to take the derivatives so I just used 1/1-x as the summation of x^n and substituted (-x^2) for x. I checked later that I got the right summation but will my professor take points off because I did it a different way?

Just for fun, I have an interest in machine learning and a lot of computer science so last year I decided to teach myself some mathematics.

Maybe one day I wont be working in a factory for just above min wage :)

I think this would depend on the professor. It is not a really good idea to use results not proved in class, especially if they making solving the question considerably easier, but he should give you at least some partial credit.
