pencil··on Ask HN: What are some Good Books you have read in past one year or so..
I like this thread very much.

pencil··on Symmetry of graphs
i think i found the solution http://math.stackexchange.com/questions/59526/symmetry-with-...
pencil··on Help me Choose: Application devlopment or Low level system programming.
Congragulations again.I'am a beginner c programmer and i don't intend to learn anything other than c and c++.I'am crazy about low level coding like firmware and device driver development.If i was in your shoes i would go for the other one,no matter the pay is low.[not that i'am rich!!]
pencil··on Ask HN:help with algebraic equation
yes i now have an quintic equation.now i can use any method to solve for 'x'. thank you
pencil··on Scale of the Universe
too good..i've added it to my favorites.
pencil··on "Calling oneself a C Programmer is like saying you're a Hammer Carpenter"
abstraction of...ya go on i realy want to know what's beneath that if there is. would be very happy if you could recommend a book which goes so deep.(deeper then that preferebly!!)
pencil··on In Honor Of Mandelbrot, A Collection Of Beautiful Fractals
hey..has it got to do with fractal geometry? just curious.
pencil··on Indian OS
hey that's a very good point.i've heard NSA makes it's own CPU,memory etc..is that true??
pencil··on Ask HN:properties of real numbers
no this isn't stupid.
pencil··on Ask HN:properties of real numbers
i know even i used to hate formal proofs!!!i assumed this might have a formal proof by not knowing that this property is based on informal reasoning. (but i personally like formal proofs!!!!!)
pencil··on Ask HN:properties of real numbers
oh ya..that looks like a formal proof!!!!!!!!!
pencil··on Ask HN:properties of real numbers
well..this gives the definition of real numbers http://en.wikipedia.org/wiki/Real_numbers..but doesn't mention even a single bit about the truthfullness of the properties of realnumbers.(to be honest i'am not in a position to come out with a rational explanation!!!!!)
pencil··on Ask HN:properties of real numbers
we are in the same page !!!!
pencil··on Ask HN:Transitivity property of real numbers
ah.that's a wise explanation .i even realised that it's just a fundamental law and not a theorem.anyways you made it clear.
pencil··on Ask HN:Transitivity property of real numbers
ya you may be right...let me do some research on real numbers and it's properties and then get back to you!!!!
pencil··on How to get a job at Google, interview questions & process
i'am sick of hearing google's interview process.a company like google with kickass problem solvers should not hire a person based on his fucked up SAT scores{to me it sounds like sad scores!!} it has to be purely based on talent,his aptitude/attitude and skills.
pencil··on The Physics of a Fighter Jet Rainbow
ok people ..can someone tell me what is that circular "thing" that surrounds the aircraft as the plane crosses the sound barrier? is that moisture or something? if yes how does it occur? an explanation on this would would really fulfill my curiosity.
pencil··on Math lectures online, Not video
hey pixcavator!!i'am impressed with your cources.But what exactly is computer vision? i'am a newbie to this.i recently developed an interest in math
pencil··on "Hello, world" in Assembly.
i would say it's a nightmare programming in assembly without going through your tutorial.!!!
pencil··on Space Shuttle and ISS transit the Sun.
kinda unbelievable..no sun spots or any other form of solar activity
pencil··on What is Hacker News?
I consider a COMPLEX problem solver is a hacker. A person who makes profound contribution to his field of interest is a hacker. A person who looks at a tree and wonders why the branches and the leaves grow the way they should is a hacker. TO SUM IT UP A PERSON WHO'S NOT WORRIED BUT CURIOUS TO KNOW HOW THINGS WORK IS A HACKER. HACKER NEWS IS A PLACE FOR THESE MEN,WOMEN AND CHILDREN TO MEET UP. (for the time being i don't fall into any of the above category as i'am yet to become a hacker!!!!!!!!)
pencil··on Trouble with logarithms and partial fractions
i've started out with calculus.(it;s been 30 hours now) and i'am enjoying it as i'am able to understand.so my plan is to continue this partial fraction problem when i reach integral calculus involving partial fractions and eventually laplace transforms. and you said my algebra skills sucks.well i partialy agree with you cause i wouldn't be able to solve limits and differentiate functions without a grasp on algebra(precalculus for namesake). as a matter of fact i've never been good at anything .i suck in everything that i do.!!!!!!!!!

by the way i'am not offended.i'am enjoying myself with calculus.i'll get back to you if i have any doubts.if you got to say something you can.

pencil··on Trouble with logarithms and partial fractions
the fun part has got nothing to do with polynomials.i'am finding it funny cause i'am taking ages to learn this basic concept .to put in better sentence a DUMB ASS(that's me) taking advice from a knowledgeable person(that's you)

by the way thanks very much for telling me that 'A' and 'B' represents polynomials.never knew it before.

pencil··on Trouble with logarithms and partial fractions
Bx+B2 ??? now it's getting funny!!!!!!!!
pencil··on Trouble with logarithms and partial fractions
3x+6
pencil··on Trouble with logarithms and partial fractions
expand B(x+2)?? but how??
pencil··on Trouble with logarithms and partial fractions
i get A(1-x+x^2) + B(x+2) = 3x-1
pencil··on Trouble with logarithms and partial fractions
first of all i don't know the significance of replacing the numerator with capital letters when decomposing partial fractions.i'am not aware of the practical implications of these problems.all i know is it'll come in handy when solving laplace transforms in the future which is used in physics/electrical etc.(that's what i'am after). and if you are curious to know why i wanna learn these..well i don't have a proper reason.i simply want to!!

i looked back at the original problem but i'am unable to figure out the values to assign to A and B.

pencil··on Trouble with logarithms and partial fractions
all right the brackets concept makes sense.

remembering a/b + c/d = (ad+bc)/bd

A/(x+2) + B/(1-x+x^2) = A(1-x+x^2) + B(x+2)/(x+2)(1-x+x^2)

correct??
