pay attention to everything, but anything having to do with properties learn them like the back of your hand. ex: log and exponential properties

also, learn your trig
know and understand the unit circle
know the identities and how to derive the others

Alrighty
When is
4<span class="math">n^{2}[/spoiler] + 16n - 65
prime ?

My main issue is how do you check if it's prime.

A nigger is trying to prove me that biology is a science

How do I make him stfu ?

I know this isnt /r/ but please more like this

How in the fuck do you solve for polynomials of degree > 2 with irrational zeros without a calculator (algebraically)?

E.g. <span class="math">X^{4}-4*X^{3}+15[/spoiler]

Rational Zero Test is useless.

Descartes Rule of Signs is useful, but does not give a direct answer.

Factoring tricks seem impossible unless you already know the answer.

This is driving me insane.

Gentlemen, I would be very grateful, if you uploaded an infographic concerning logarithms. I skipped school, when they were learning this subject and used some book to write down basic identities, but now that copybook is gone, and I just want to always have a quick and convenient piece of information available. Picrel is the ideal analogue of what I want. Also would be nice of you to mention some decent problem book on the subject, just to "feel" it, if you know what I mean.

What's everyone taking this fall at university? Also, general study tips if you have them.

Differential Equations
Real Analysis
Inorganic Chemistry
Spanish Translation
General Chemistry I Laboratory (lol 2 year gap between class and lab)

Just going to start watching them now, thanks.

I'm more interested in applied physics anyways, so I guess that's good for finding a readily available job.

Use the half angle identity I would assume. Take this.

So, what are you doing right now? Trig identities? Those are mostly memorization. Pic related.

Hey /sci/.

Question 4, the line that says:

"Observe that a^2 + b^2 - 2ab = (a+b)^2 > 0"

Shouldn't it be "a^2 + b^2 + 2ab = (a+b)^2"?

Pic not really related.

Does anybody know chemically or biologically why people generally don't get high the first time they smoke pot?

ramanujan
riemann
euler
gauss
newton

just thought id state the obvious

Print all three of these out, and use them to memorize equations and formulae as you work through the books. Also, add onto them when you find something you don't see.

Good luck to you my friend, if you work hard it should not be a problem to pass.
