Sorry for the late reply Greg , I have been searching for a good Pre algebra book for the past 1 month I tried a lot of books but there is not a single book i can still recommend . But this website here is a good one , https://www.math-only-math.com/ I have been practicing from it from...

Are there any good websites or tutorials in PDF format out there that helps to improve mathematics from basics ?

Mark44 I understand this now . Thanks a lot for the detailed explanations .

In a pdf online , i found this . LCM 1. Find the prime factorization of each number in the group. 2. Make a list of ALL factors, raised to the HIGHEST power that appears in any factorization. 3. Multiply out. GCF 1. Find the prime factorization of each number in the group. 2. Make a list of...

After trying to learn computer science and numerical methods . This is what i have learned from my past experiences . Science is a differential equation. Religion is a boundary condition - Alan Turing

Yes , from the beginning .These are all the only things i am trying to learn ,nothing more .

What about this book ? Hugh D Young_ Roger A Freedman_ Albert Lewis Ford-Sears and Zemansky's university physics _ with modern physics

LCM of Numbers Fractions Rational expressions GCF of Numbers Fractions Rational expressions

I found something nice here . http://www.mclph.umn.edu/mathrefresh/logs.html

Thanks a lot for all the replies :-)

Thanks for the reply , Found some good materials in khan academy https://www.khanacademy.org/math/algebra2/exponential-and-logarithmic-functions/introduction-to-logarithms/v/logarithms

I have a couple of college algebra textbooks , but none has some proper intro to logarithm basics . I like to keep a book for logarithm alone , i see some online PDF's on logarithm , but all are sort of messed up . Please help

Mathivanan , Thanks for the reply . I was mostly after finding LCD of the denominators of rational expressions and equations . I have more clarity now .

No , maybe i should . I got another book though . Its called "M. Dugopolski -Elementary and Intermediate Algebra" .Looks like a really nice book :-)

OK , Thanks

To calculate an LCM for a rational function, follow these steps: 1. Factor all denominator polynomials completely. 2. Make a list that contains one copy of each factor, all multiplied together. 3. The power of each factor in that list should be the highest power that factor is raised to in any...

Thanks for the replies . Mentor note: Unrelated images have been deleted. So , x is electrons x is a quantity x is binary x is a point mass object x is digital logic Is this an OK definition ? Steps to Find the LCM of Two or More Rational Expressions 1. Factor all denominators completely. 2...

Thanks a lot for that really long explanation . I understand this part properly 1. Factor all denominators completely 4x = 2.2.x , x2 = x.x , 2x2 =2.x.x So , 2. The LCM is the "product" of unique ( being the only one of its kind; unlike anything else )"pairs of irreducible factors" from...

Thanks , Steps to Find the LCM of Two or More Rational Expressions 1. Factor all denominators completely. 2. The LCM is the product of unique prime factors from the denominators, where each factor is raised to the highest power to which it appears in any denominator. Can somebody show me...

Thanks for the reply , In the first equation , why is 4x2 the LCM ? What are the steps involved to find LCM like that ? Same question here , i don't understand taking the LCM part properly ?

OK , I have three questions I was a computer science student , so i am a bit confused about some terms . What is a variable x ? x is a quantity x is binary x is a point mass object x is digital logic x is electrons The other is when you try to find the "pairs of factors" of a number . You...

Thanks , i will check those too :-)

Thanks , but i was looking for something simple . I think i found a good book online called Glencoe - Algebra 1-McGraw-Hill It looks really good for my needs :-)

Ok thanks , i have a couple of college texts somewhere in my cupboard , maybe i should refer that once more :-)

Can someone recommend me some books that have practice problems for algebra with answers ?

Thanks for the explanations :-)

We had computer oriented numerical methods in C programming language in our syllabus , so i went through at least 5 books , lots of online materials on C . Some books are very minimal like the Official version , The C programming Language. By Brian W. Kernighan and Dennis M. Ritchie So , When...

Thanks for the reply , Currently i am only following the materials available from these resources . http://ncert.nic.in/textbook/textbook.htm https://2012books.lardbucket.org/books/beginning-algebra/ http://ins.sjtu.edu.cn/people/mtang/textbook.pdf Most of those resources don't have...

Get all the books you can possibly find :-)

Thanks for the reply , One reason why i like this forum is that you always get a fast reply no matter how stupid your questions are . :-)

Methods of factoring . Method of common factors Factorization by regrouping terms Factorization using identities Factors of the form ( x + a) ( x + b) Factor by Splitting Is this all the factoring methods out there ? Or are there more ? I am also looking for a book with lots of...

I also found something here Factoring and Solving by Factoring https://2012books.lardbucket.org/books/beginning-algebra/s09-factoring-and-solving-by-facto.html :-)

How about this one ?

Thanks a lot :-)

Thanks , but Its not opening in my place , i had to use a web proxy to see that website . don't know why it is like that .

Like this book ? https://2012books.lardbucket.org/books/beginning-algebra/

Where can i find some worked out practice problems ?

Thanks , Found a good material online . http://ncert.nic.in/textbook/textbook.htm?lemh2=3-6

Right , sorry about that .

What is a differential equation ? It is an equation involving an unknown function (solution) and its derivatives This much is OK , right ?

the "wave equation" and the "heat equation " are such types of equations right ?

Ok , The independent variable is x. The dependent variable is f(x) In this , The function 1 , 4 , 5 are functions of several variables right ?

Which one is the independent variable and the dependent variable here?

Thanks :-)

Thanks :-)

Thanks , Same things right ?

Thanks , First you have a function f(x) Then you can take the derivative of that function from first principles Then you get f'(x) or dy/dx That dy/dx , the slope of the curve (derivative) at a given point is a number . I have been unnecessarily thinking about the cause behind why...

It is ok , i sort of understand it with my new avatar . Some points i tried to narrow down . Differential calculus - which is looking at the instantaneous rates of change of objects with respect to some variables. We have the notion of the derivative of a function The slope of the curve...

I keep thinking of naturally occurring things whenever i think of derivatives , differential equations and partial differential equations .Like electricity , magnetic field . I am always like if there is a derivative in a differential equation , how could have that happened ? what could have...
