I hate e.

[rarbass]

Really? I've found that e makes calc a lot easier since e^x is it's own derivative (and antiderivative), and the derivative of ln(x) is 1/x. I'm just in calc 1 though, maybe it gets more complicated? The trig functions make things a bit tricky though.

No you're right. I think it's my whole hatred of Calculus in general that makes me despise the very sight of e. But trig functions are infinitely worse.

The week we learned trig stuff back in high school, I had my appendix out, so I was never able to catch up and properly learn. So I've never found them easy.

 

[rarbass]

I don't like C, or any random constant I choose for integrations. Simply because I randomly forget it and lose points.

Ahh that sucks!!

e wasn't so bad. Really I think the things that screwed me over the most in calculus were the trig functions, it took me way to long to figure those out...

Same here, I would go into a test in Calc 1 knowing a concept, and get completely screwed over because they put trig into an otherwise simple question.

So what you're saying is, E is a plague upon the face of the Earth.

No no...being that e^x is it's own derivative AND anti derivative, it's not nearly as bad as Social Networking (Facebook specifically, Twitter MORE specifically). But I'd rather sign up for Facebook then have anymore Calc classes.

i decided to go with computers because they only count to 1. But they still require calculus for computer engineering....whats up with that?

Yeah I'm in Computer Science. Why do we need Calculus?

are you friggin' kidding?

exponential functions are the easiest damn functions to integrate! (besides "1.")

i don't think you're hating the playa (in this case, the playa being "e")--i think you're hating the game.

(the game being math.)

yeah you're right. lol

That's what i was going to say... i LOVE e! Now, if you're in highschool and in calc 2 like me, once you start getting into parametrics and polar curves, you're gonna WISH you could see e again

'j' is also used to denote -1^(1/2) (i.e. imaginary numbers) in situations where 'i' has other uses, like in electrical engineering equations where 'i' will denote current.

True that, I tend to use them in a pure physical sense. Well, thankfully I haven't had to do much in the way of quantum mechanics or had to sort any more surface plasmon problems

Ahh yeah, that would definitely throw things off. Trig is actually not terribly hard once you learn it (IMO) but in calc the less common ones require a bit of memorization and can make your derivatives and integrals a bit ugly.

Can I ask what the purpose of the "less common ones" is? For example, if you already have 1/sinx, why make it cscx? Sure it looks a bit nicer but now you need a whole new derivative to memorize...the same goes for the rest of them.

 

[john turner]

if you get involved in control theory, like with regard to robotics, you'll probably bump into mason's theorem and laplace transforms. w00t. nothing like substituting multi-order polynomial expressions for multi-degree differential equations.

god i loved that class.

My favorite integrations are ln(x)dx and Sin(x)e^x dx for the record.

And actually what I hate is when you have pair trigs, ie: Sin^8 (x) dx, since you have to linearize the whole deal and it takes an eternity. Trig is fun otherwise, I'm having a lot of fun with hyperbolic trig, sinh, argcosh, etc.

Now prove that argosh(x)=ln(x+(x^2+1)^1/2)
no need of integ. with that but it's a good calc test imo.

In my view the way to catch back up is to do a ship load of problems in that area. Get a Schaum's Outline which provides a lot of problems to work on, and is not too expensive. Use the outline as a reference book as well, for the formulas that you need. This will cause you to memorize the important formulas (definitions of the trig functions, basic identities, etc.) without wasting your time trying to memorize them by themselves.

The good and bad news is that this can be overcome by massive work.

Problem there is d/dx(1/sinx) doesn't make it any easier--it's the same as d/dx(cscx) and you still have to memorize it. Also, inverse trig functions get tricky because they introduce radicals in fractions and whatnot (and they involve more memorization.)

quaternions: madness
Oliver Heaviside showed a better way.

That pesky "e" is just a warning that you need to be on the lookout for some eigenvalues that have escaped from the unit circle and may be headed your way.

You may also learn that integration by parts is more than just a fancy school busing scheme. Read some "Calculus Made Easy" by Sylvanus P Thompson. Dr. David Derbes showed us that great little book.

I don't get it...….

Now prove that argosh(x)=ln(x+(x^2+1)^2)

Are you sure you didn't mean argcosh(x)=ln(x + sqrt(x^2 - 1))?

'j' is also used to denote -1^(1/2) (i.e. imaginary numbers) in situations where 'i' has other uses, like in electrical engineering equations where 'i' will denote current.

i've always found that to be extremely lame.

about a year ago, i had an equation that used "alpha" three times to represent (1) the fine structure constant, (2) dirac matrices, and (3) the spin-up spinor. surely engineers can learn to live with context-sensitive uses of "i." (in fact, i constantly see "i" used as both an index and as the square root of -1 on the same side of an equation.)

you mean "arccosh," right?

god i loved that class.

i'm taught my students how to solve partial differential equations with fourier transforms today. same sort of deal, except it's incredibly easy to use in three dimensions.

i've honestly never seen a laplace transform since i was 19. and that was after even taking a course in complex variables.

but i guess a laplace transform is just a wick-rotated fourier transform, anyway.

lol. that's why engineers build things that work and physicists...have awesome hair. ( meaning they're used to having their stuff read by folks that actually don't know what's going on. ).
