i think 0-1=x.
x is every point on the complex plane, including the infinite and finite in magnitude.
and
0/0=0*any number on the complex plane
0/0=0*infinite=finite
0/0=0*infinetsimal=0
0/0=0*finite=0
so 0/0 is every point on the complex plane with a noninfinite magnitude, including zero.
my main question: is there some mathematical formula that leads to a great song? be it a beat, melody, etc. what is the mathematical difference between dissonance and connosance? we know that listening to classical music at a young age results in high math scores. but why?
i have listened to...
Hi. i dont know alot about chemistry so bear with me.
the bond is between a member of the carboxyl group and the amino acid lysine.
as i understand i need an enzyme. what readily available enzyme would suffice?
would protease work?
It is possible.
If the gun is pointed straight up, the total magnitude of the velocity vector upon impact will be the terminal velocity.
But, seeing as nobody was hanging onto a steeple and shooting up into the air from the top of the church, it is obvious that the gun was not pointed straight...
alcohol isnt my intoxicant of choice because alcohol has lowered my inhibitions and caused me to do things that have gotten me in trouble. personally, i prefer cannabis and dextromethorphan(cough medicine). lately however i have done neither due to being on probation. btw, dextromethorphan...
a derivation of the formula for arc length is simple enough:
given a function f[x], find the length of the arc from x0 to x1.
lim(x1-x0)/n=dx
n->inf
x1
S=^{i=n-1}_{i=0}\sum\sqrt{(x+(i+1)dx-(x+idx))^2+f(x+(i+1)dx)-f(x+dx))^2}

i am a recovering runescape addict. luckily i havent logged in, nor thought of logging in in over 6 months now. it took over my life. its far more addicting than any drug ive tried. all i thought, slept, ate, drank, and crapped was runescape. i wish i never started.

"a righteous atheist is morally superior to a righteous theist"
what do you think of this statement?
suppose there are two people, person A and person B.
person A believes that there is no afterlife, no god, nothing once you die. any good actions you do will not be rewarded. any bad...
in general they would range in complexity. im writing a program that finds the arc length of a level curve of some function f[x,y]. do you mean every implicit curve has a parametric representation?
suppose i want to find the following integral:
7
\intx dx
3
now suppose for some demented reason i decided not to do it straightforward and get (49-9)/2=20
instead i use the substitution x=u2+4u+5
giving
u1
\int(u2+4u+5)(2u+4)du
u0
u1
\int2u3+12u2+26u+20 du
u0
the indefinite integral is...
and if i serve time it will severely affect my ability of what to study. my mathematical interest is numerical analysis. (for example: anybody ever tried doing 1 million iterations of runge-kutta by hand?) without my computer to write programs that test algorithms ill be lost. but i guess that...
thanks for all the help. i generally use mathematics as an escape from my life, not a means of moving my life forward. Whenever i try to go forward in my life i feel alot of anxiety for some reason, and im afraid that studying mathematics for scholarly purposes rather than for recreational...
i guess i have found an escape in mathematics and physics. it allows me to avoid thinking about my life. i could turn that into something productive but in order to do that i would first have to take my college entrance exams. i know that i need to score phenomenally on my tests, but im not...
it seems like u should be a physicist then. but you will find that linear algebra is VERY important to calculus. escpecially when solving differential equations they are very intertwined. if you find linear algebra boring, look up the eigenvalue theorems. i find them very fascinating because...
I tend towards alot of death metal/industrial metal. im not goth or anything, but i like it because it sounds real angry, and that gets me pumped up. i mostly like it for the atmosphere.
im 21 years old and i have done absolutely nothing in my life. i havent taken the sat,act, or any type of college entrance exams. i am stuck in a rut and i dont see a way to get my life moving. i have made so many mistakes in my life. there are so many regrets i have.
i remember not having...
So theres no general formula/algorithm? bummer. there is no information about the curve other than it cannot be parameterized(and trivially, cannot be put into the form y[x]
this is really perplexing. how can it be exact? simpsons rule uses quadratics to approximate the curve. how can it be exact if im approximating a cubic with a quadratic?
?
i used the implicit function theorem to find dy/dx, then applied that to the arc length formula, but i have to integrate with respect to x and there is the implicit function y[x] inside the radical.
also, if it matters, the curve is assumed to be closed.
Hi. i wrote a script that finds the definite integral of a function using simpsons rule.
right now the function to be integrated is defined as 2*pow(9-pow(x,2),.5).
but this is very inconvenient to me because i must edit the program each time i want to find a new integral. my question is how...
suppose i have a nonconservative vector field.
and there is a path going from point A to point B.
How do i determine the path taken from A to B such that the line integral is maximized?
edit: actually after thinkin about it, this might be an undefined problem unless there is some constraint on...
