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
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...
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...

Are all these called root finding algorithms? All of it ?

i have some confusions with some terms ,especially terms like simplify , solve .
Factors ,GCF ,LCM
Should i start learning it like this ?
Simplify fraction
Simplify Algebraic expression
Simplify Algebraic fractions
Solve Algebraic equations
?
Functions are pretty simple things , they just express a relationship between two different quantities
How do i express this function in terms of y(x) = something ?
First of all there is an equation
Then there is the derivative
Then there is a point slope formula to find the equation of the tangent line
Point slope formula to obtain the tangent line .
y=3a2(x-a)+a3
Then Plug in the x coordinate into the derivative to get the slope
f'(1) = 3(1)2
f'(1) = 3...
If you write a polynomial as the product of two or more polynomials, you have factored the polynomial.
Here is an example:
how do i factor a polynomial ?
can somebody explain this step in detail ?
A number can be factored into a product of its component factors
A number can be factored into a product of its prime .
But, What exactly is a prime number ?
Prime numbers are numbers greater than 1 that are evenly divisible only by themselves and 1
Is it a number that can only be evenly...
