pencil··on Trouble with logarithms and partial fractions
in 1 and 3 those extra square brackets aren't necessary.

secondly i'am trying to solve this as it will help in working out laplace transforms in the future.

i went through the partial fraction tutorial in wikipedia and khan acadamy and i'am able to solve the following problems.

1) x/(x+1)(x-4)

2)3x+1/x^2-6x+8

it appears that the above problems are straight forward.all i have to do is solve for 'A' and 'B' after writing them as A/x+1 + B/x-4. but the problems which i have posted are not .i've tried to jiggle it around a lot of times and going no where.

with regards to the second question i really don't know how on earth to factorize x^3+1 that's in the denominator.

lastly i'll be really happy if you wanna test my ability in math.i'll answer your questions if i'am capable of so that you can suggest what needs to be done next. In fact i believe in learning math the hard way!!!

pencil··on Trouble with logarithms and partial fractions
one of the best tutorials on logs i've ever come accross.thanks a million!!!! please look into my partial fraction problems when you get the time.so far i've been able to solve a couple of them but the above mentioned one is bothering me a lot.

i'am assuming this would end up in some number called 'e' which i came accross somewhere in the past.please help..i'am not sure what that number means and how to get it

i'am not able to solve t=log(u).not even a single step sorry

i'am assuming this would end up in some number called 'e' which i came accross somewhere in the past.please help..i'am not sure what that number means and how to get it

i'll be back in 45 min

now i have the solution for y in x=10^y

here it is:x=10^y

subtract 10^y from both the sides

x-10^y=0

now subtract x from both the sides

-10^y = -x

divide by -1

-10^y/-1 = -x/-1

= 10^y = x

take log base 10 both sides

log10^y = logx

= ylog10=logx

y = logx/log10

x^3+5=x^8

t^3 * t^3 = t^6

i guess it's u^6

g^2+4g+4

not sure abt (z-3)^3

expanding (z-3)^3

could it be: (z-3).(z+3)^2 ??

=>(z-3) (z^2+3z+9)

ya i've tried them

i completely agree with you sir and i really appologise for not responding to this thread http://news.ycombinator.com/item?id=1107996 to be honest with you i really don't know where i stand .what's my level of competence. i recently gained interest in math and physics because i regret not taking these two subjects seriously back in college.now i work for a bank which pay's peanuts.i don't intend to get a job which helps me build my math/physics skills,i just wanna learn it because i have a burning desire to learn it.it's as simple as that. yes.math requires hours and days of practice which i'am religiously doing but it's not enough for me as it's very evident by the level of knowledge/intellect that i possess. with that being said the number of ways arranging the equation log(x)+3=2t hmm.. log(x)=2t-3 am i right??hope i'am not bullshitting you.

by the way the only definition of logarithm that i know is 'log is inverse of exponents'

pencil··on Trouble with logarithms and partial fractions
thank you so much for your response,actually rearragning the terms to find 'b' gives me 3logb = 2loga - 5 {upon subtracting 5 from both the sides}. this is where i need help.please look into my partial fractions problems as well if you got the time.
pencil··on Trouble with logarithms and partial fractions
Thank you so much.what about the rest??any idea??
pencil··on Trouble with logarithms and partial fractions
i couldn't find any book that clearly explains logarithms and partial fractions nor khan acadamy was able to find a solution to this.
pencil··on Ask HN: How do I become smarter?
when i was 19 even i used to contemplate on how to get smarter but ended up becoming a piece of rotten vegetable.now at the age of 25 i believe in doing volumes of work and imagining things.that's the only way of becomming smart.
pencil··on Understanding the linux kernel
thanks for the advice.your profile looks interesting.you say physics and math were minors in your degree.i intend to be a computer scientist one day.do you recommend that i study physics and math?
pencil··on Code to electrical signal
great..thank you very much .yes i'am really interested in knowing even further..
pencil··on Code to electrical signal
thank you so much
pencil··on 11 Ways to Successful Innovation
excellent philosphical thoughts.really makes a lot of sense.
pencil··on Electrical engineering
to be honest i 'am capable of solving the above problem without any dificulty as they are pretty straight forward.to answer your question i don't have the time to go to a university nor a local library as i need to work to feed my family.but i can buy sufficient time to study on my own .anyways thanks a lot for your advice ,if you have further recomendations i'll be really glad to hear from you
pencil··on Electrical engineering
well..i'am 25 years old and i'am very much eager to learn,i'am pretty good at algebra but i've got no knowledge in physics nor the essential math needed to learn physics and essential physics needed to learn electrical engineering,i'am stuck
pencil··on BIOS
i'am also interested in knowing what a microcode is {wikipedia doesn't have much on this} what's it written in ?
pencil··on Prerequisite for learning assembly
thank you so much for all your advice .i'am curious to know if companies like microsoft and a couple of hardware companies still use it.
