Re: Infinity * Zero = Any Number ARGUE HERE

Tell me if you've gotten to Calculus or beyond yet.

The list of formulas to memorize for derivatives is over 100. Just for derivatives. There are 100 more for integrals. There are probably hundreds more for other things.

Do you honestly see this as necessary? Do you honestly think you can rely on this knowledge if you're in an emergency situation? What if you confuse 1/x with x/1? What if you confuse 2x with x^2? What about cotangent with cosecant?

Professors seem to think you NEED TO KNOW these things, and you're telling me those professions NEED TO KNOW these things, so this is not an unrealistic number of formulas AT ALL.

OH NOT TO MENTION all the rules for finding them. Quotient Rule, Chain Rule, Product Rule, Power Rule. DEFINITELY NOT HARD TO CONFUSE THESE HAHAHAHA.

Get memorizing. If you can't tell me what the derivative of 5x^9arccot(6x) +10x^2csc(3) is within five minutes, the world could end. No calculators, please.

Oh and don't confuse any of those with these.

Wait, that's calculus?

****. Learning college level discrete math is actually kind-of fun, but calculus looks really boring and stupid.

hahahahahaha

Also, it makes me feel all fuzzy being able to not only comprehend, but actually have already known that entire wiki page when at this time last year I would just stared blankly at the screen.

Carbo: Calculus is basically math that involves rates of change. You've probably briefly looked at First Differences and Second Differences - that's extremely basic calculus. It's all about finding out how quickly your graphs are increasing/decreasing and how fast that's happening (i.e. velocity, acceleration). You NEED it for physics, and it has random bits of use in other pursuits (maximizing profits, other optimizations such as minimum surface area with maximum volume).

Re: Infinity * Zero = Any Number ARGUE HERE

There's a big difference.

Put it this way. Whereas Reach was able to pass only by knowing similar problems beforehand, I failed because I knew all of the material but managed to get confused or messed up on trigonometric derivatives and integrals.

Long story short: I know Calculus and failed Calculus. Three times.

Just because I knew similar problems doesn't mean I didn't understand calculus >.>


It's pretty hard to fail a course. How on earth did you fail it 3 times? I call that pure lazy. Trigonometric derivatives take all of about 5 seconds to memorize, and you can derive all of them from scratch if you forget one.

And from personal experience, calculus in college is easier than in highschool.

86 in highschool calculus 95 in university.


Then again, essentially what our highschool teacher did was harder. He allowed calculators and in doing so made all of the tests far harder than anything we would be asked without a calculator.

One of my friends failed the first calculus class three times and then got A's on (I think) every exam the third year. Pretty amazing slacker . As Squeek said, College calculus is a lot of memorization before applying everything. However, as Reach said, it doesn't take too long to memorize the stuff.

I am staring blankly at the screen =(

If there's no implicit way to use a mathematical formula or if it doesn't have anything really interesting or concrete about it, I'm immediately turned off, which is why I take a bigger interest in discrete math subjects.

Re: Infinity * Zero = Any Number ARGUE HERE

To me, that's (that long post by Squeek) a distorted version of calculus. I prefer just knowing the formulas for exponential, logarithmic, sine, cosine, and then also the power rule, chain rule, quotient rule, and product rule, and logarithmic differentiation, and I feel I can differentiate just about anything that's differential from those. Integrals require knowing a lot more than that, though, even though a lot of it is just changing how the integral looks into something you know how to integrate.

Re: Infinity * Zero = Any Number ARGUE HERE

Different high schools and colleges do various subjects totally differently anyway, so it's kinda pointless to say that "all high school Calculus" or "all college Calculus" is done a certain way, because it's not.

Re: Infinity * Zero = Any Number ARGUE HERE

The only calculus that's worthless is Calc 3, which in my Uni is most concerned with Infinite Series. Worthless pieces of crap, they is. If there's a way for you to avoid series, do it, but take the other calculus courses.

Re: Infinity * Zero = Any Number ARGUE HERE

I love maths, its so lovely, ive just finished a practice paper for my exam thats coming up and was doing some iterative formula and differentiating natural logs and such, was great fun. Who cares if some maths you learn is pointless, its all fun. Yay for maths *huggles*

Re: Infinity * Zero = Any Number ARGUE HERE

Infinity = not a number, just a symbol meaning "never-ending", as per the actual sign itself, if you were to trace it, it would never end, no?

This thread is now about mag-rails.

8 never ends either. Neither does 0. 6 and 9 both can not too.

I have another QUESTION: What if there were sticks layed out a foot away from eachother going on in a straight line forever... and inbetween each stick are 3 pebbles. Would there be more pebbles and sticks? the other way? same?

Same.

EDIT: Neither you nor Squeek should go to Quantum physics class...

Re: Infinity * Zero = Any Number ARGUE HERE

Uh, with regards to the very strange stick question...

Do it five times and see who's winning.

-...-...-...-...-

Looks like there's not even any logic required to make this assertion.

Now, back to the discussion at hand: Calculus and how pointlessly crappy it is.

Calculus is the reason I had to change majors. I went to class, took notes, did homework, studied. THIS IS THE ONLY CLASS I EVER TRIED HARD IN. And I failed three times. Not only that, but I had five more math courses after that--one of them being Calc III!

Then I take Astronomy II and pass without even attending a single lecture.

Now that I'm in IT, I go to all of my classes but I never take notes. I never do homework. I never study. Heck, I have a class in ten minutes and when I go, I bring my laptop because the teacher is too boring to listen to for three hours.

I have straight As. AND I'm in a Math course. Discrete math. To me, this is one of the most applicable maths to anyone's career. Ever.

Spyke, why would I? Science classes are just as stupid and pointless as math courses. The reason I didn't go to Astr II lectures was because A) The professor knew nothing and only read things straight off of a powerpoint slide and B) she tried to teach us utterly pointless things about astronomy. WHO CARES about the mass of a small particle and its distance from earth and how fast it travels and how many stick into the earth and how hot it is and ugh.

The science course I'm in right now is the greatest course ever designed for science. It's just the need-to-know information on every science. It NEVER goes in-depth on any single topic because it's pointless to do so.
