Or you can use a strategy that has been put forward in a book here recently in Norway. A guy who's world top at memorizing cards use two techniques: travelroute and images.
You use familiar places, like your home, and walk through each room. You'll recognize these rooms very well because it's...
yes, i am. Yeah, I figured.
Like this right?:
\int 5 x e^{x^2}dx = 5/2§2xe^(x^2) = 5/2§ (and as in opposite of the above e^(x^2)*2x) = (e^(x^2)) , which gives simply 5/2(e^(x^2))+C.
(e^u)`*u` I'm making a fault here? no chain rule in integral? e^(x^2)=e^(x^2)? , but why isn't chain rule being used? (like in §e^(3x-2)dx=(1/3)e^(3x-2)+C.) it looks like it should, heh. And how do the x^2 dissapear..
Where do I find LaTeX?
Yeah, I meant chain rule. in is natural logarithm, e^inp=p.
My try went:
§5x*e^(x^2)dx=
5/2§2x*e^(x^2)dx (cause here is where you 'use it', right? =
5/2*2*(1/(1+1))x^(1+1)*(e^u)`*u` (chain rule) =
5/2*x^2*e^(x^2)*(1/(2+1))x^(2+1) =
5/2x^2*e^(x^2)*(1/3)x^3+C.
Homework Statement
Solve (e^(x^2))` , use this result to solve §5x*e^(x^2)dx
Homework Equations

The Attempt at a Solution
(I'm alittle confused as to...
uh, are you joking with me, or am I writing down the question wrong(cause I know I have a bad habit of not reading the question at probability well enough)? Cause that was the way I was thinking as you above.
Yeah, b| the probability of that the eldest is a brother, and the two youngest girls. That is also just one outcomes yes? So that should give 1/8. But the answer writes as 0.121, which is not 1/8. ???
Jeeserssweesers(for a lack of a better word), probability is confusing.
Homework Statement

Another guy that wants to shout out his oppinion without reading all that's before him.
For me it is different in that I find much meaning, but I also feel small. I'm supporised when someone says they can't find meaning in anything for to me there is so much. Maybe if you can't find a meaning...
