Alright then, I'll help you out as much as possible.

The answer to that last one is "nonexistent".

You see, for x > 3, f(x) = (x-3) + 2 = x-1 (which has derivative equal to one), while for x < 3, f(x) = 2 - (x-3) = 5 - x (which has derivative equal to negative one). Therefore, the derivative does not exist at 3.

Oh yeah, as far as your skills go, do you know the "power rule" for differentiating (that is, can you differentiate stuff along the lines of 3x^2 + 2x or such quickly and easily)?

Perfect, thank you, I thought it was 2 for some godawful reason.

Yeah, I know all the derivative rules, and I'm decent at derivatives, but now we're getting into the stuff that's like "the derivative of sin x = cos x, derivative of cos x = -sin x, derivative of sec x = tanxsecx" and it's just REALLY confusing to me.
I HATE trig, if that isn't already apparent XD

MK, at the back of my maths textbook is a "table of derivatives/integrals" which has a list of all the basic derivatives and integrals for common functions. If yours doesn't, I suggest googling "table of derivatives and integrals" and printing off one. That helped me memorise most of the basic derivatives for exponential, log, trig, etc. Down the track, you'll probably have maths exams where you're permitted to take in a cheat sheet, or one is provided for you.

Heh, trig is annoying.

The way I do trig derivatives, is I just remember the derivative of sin(x) is cos(x), cos(x) has derivative -sin(x), and I use the product/quotient rules for everything else. Takes a little longer, but I know it's right. (Or I just look them up on my computer. :p)

Another good thing to remember is that sec, cosec and cot are just equal to 1/sin, and the denominator is determined by the 3rd letter (i.e. sec is 1/cos; cosec is 1/sin; cot is 1/tan)

The Rockin you never knew...

I may as well show you all the true facts about me




and my awesomeness

James Cameron wanted Rockin to play the Terminator. However, upon reflection, he realized that would have turned his movie into a documentary, so he went with Arnold Schwarzenegger.

Sticks and stones may break your bones, but a Rockin glare will liquefy your kidneys.

Rockin's tears cure cancer. Too bad he has never cried. Ever.

They say curiosity killed the cat. This is false. Rockin killed the cat. Every single one of them.


....sorry Tom =/

so remember.

when you're thinking of awesome ****** men.

Just remember you'll think of Rockin

I ****ing love Megaman, and apparently I ****ing love watching Megaman 10 kick Omni's ***.

Seriously though omni you are hilarious to watch and I hope you do more Let's Plays (perhaps more classic Megaman?) I was on the edge my seat rooting for you against Strike Man... and your apparent arch nemesis, Chin Man.

Also the part where you bad***ed your way through the section after Chin Man round 2 was just impressive last straw John McClane ****.

Hit me up on AIM when you upload more stuff.

I'm going to take a step back from playing Mafia games for a little bit. I sorta wanna move from playing-->hosting. I LOVE hosting, and I realize, I need to reevaluate some things before I attempt to play again.
Maybe DGames Mafia was my first "Wow you were TOTALLY off" game, but it's discouraging.
Gonna start planning a new game to host, it's gonna be fun ^_^

I wanna see Omni do Megaman 9 (which has the best weapon set of all time. OF ALL TIME.). Stages were a major pain, but those weapons were seriously awesome. Every one of them was seriously useful outside of boss battles. (Jewel satellite was the best though. Equip one of those, and you could basically go through half the screens without worrying about minor enemies.)

In Megaman 10, the charge and slide with protoman is NOT worth the double damage. Maybe for a REALLY elite player he'd be good, but not for me. I got through 5 or so stages before getting bored and giving up. Besides, the weapons there weren't nearly as useful.

Oh, and Omni... try doing sheep man first. It's a bit easier...

I trust OS on this one because the way he sounded in saying it was kinda like a war-ravaged veteran, speaking through a filter of nightmarish trauma, from pure hellish experience on the battlefield -- envisioning the dismembered limbs and exposed organs of his comrades and himself catapulting in every direction.

That's what a megaman player sounds like when they talk about megaman.

I like to start with Nitro man. I just thought his stage was easier and his boss pattern was simple, and his weapon is somewhat useful at least, or more importantly if you run the weakness cycle it gets you to blade man faster. Triple Blade is by far the best weapon of ten. Course, its not like blade man's pattern is that hard...

Are you nuts? That guy's stage is a killer. Sheep man has by far the easiest attack pattern and stage to start with.
I go through Megaman games with buster only trying not to take damage from boss fights; Blade Man is pretty much the easiest one in MM10. You don't have to move more than a few steps during the entire fight. Plus you can spam his weapon in the stages if you want.

I was pretty disappointed in the weapons this time around. Last game I'd be using different weapons a ton of the time, this time I never really used them except for bosses. For example, Chill man's weapon, the chill spike is a one-trick weapon. It will help you out a ton on
the truck parts of Nitro man's stage, and is good against nitro man himself
, but where else are you going to use it?

It helps for
the trucks
? Really? I didn't know that...

But yeah, chill spike is the worst mega weapon ever... Ok well one of the worst. It is
final wily
's weakness though.

hey, can ya avoid the spoilers please? (in terms of weakness weapon over bosses)

Omni wants to go play this game in a blind, so let's make sure it stays that way.

I should do a let's play of megaman zero sometime....That is, if i can figure out a way to record my DSi.

Everytime I watch Omni's videos I hear his "porn yes".

YEEEEAAAASSSSSSS.

Then I laugh and IM him.

Alright, MK, here's what you do.

The key step in simplifying that monster

((x^2-6)^6*5x^4 - x^5(6(x^2-6)^5*2x))/(x^2-6)^12

is to realize that both terms on the top have (x^2 - 6)^5 in them. So, simplifying that out, we get

((x^2-6)*5x^4 - x^5(12x))/(x^2-6)^7

Now the top is simple enough to multiply out completely, so we get

(5x^6 - 30x^4 - 12x^6)/(x^2-6)^7

(-7x^6 - 30x^4)/(x^2-6)^7

So, when the bottom of a fraction is f(x)^n, where n is a natural number, remember that you should be able to cancel out f(x)^(n-1) from the top and bottom after applying the quotient rule. That helps the algebra a lot.
