Hi all, With reference to this post http://news.ycombinator.com/item?id=663791 Please advice nice books on algebra.you may even include all possible algebra books that you've read. Thank You Alok

any idea on how to solve this equation 2x(4-x)^(-1/2) - (4-x)^1/3 = 0..i could somehow simplify and reach 2x-(4-x)^5/6 = 0.now i don't know what to do

i've already mentioned that i have a burning desire to learn math from the ground up in my previous posts. to completely understand geometry is it worth reading ALL VOLUMES OF EUCLIDS ELEMENTS? if so how do you go about…

Hello, The addition property of real numbers says if a=b,c=d then a+c=b+d.can someone tell me why is it true? is there an algebraic proof for this or should we accept this as being true based on inductive reasoning?i…

Hello HN, I recently finshed reading stroud's and john bird's engineering mathematics.but i want to continue to read as much as math books possible.(not sure what the motive is!!) I'am really curious to know your…

Hello HN, The transitivity property of real numbers says if a>b,b>c then a>c.but when i test this property with real numbers it give's me false results.let a=1,b=2 and c=3 then the transitivity property says…

Hi, I'am damn curious to know if the sun rotate's on it's axis.also is it true that it revolves around the milky-way? if so does it take the entire solar system along with it?what really happens when the entire solar…

Hello HN, I have now gained an intuition of solving a simple equation involving implicit differentiation.example x^2y = 5 where y is considered to be a function of x even though it's not quite obvious.(it's not…

I'am willing to learn some parts of the linux kernel just for fun but i'am not good at c programming.is there anything that i should do before i get my hands on the kernel? are there any good books?

how does a computer program that we write eventually gets converted to electrical signals (after turning into zero's and one's)and flows along the bus to wherever it is destined to?what are the steps involved in this…

Hello HN, Please suggest books which teaches all(fundamental) aspects of electrical engineering,books which teaches essential physics and math

i understand that BIOS is a small program written in some language and stored on a chip/flashmemory.can someone tell me how does this instruction written by us gets stored inside a chip made of transistors?how do they…
