Calculus
The branch of mathematics that deals with the study of continuously changing quantities, with the use of limits and the differentiation and integration of functions of one or more variables, is called Calculus. Calculus analyzes aspects of change in processes or systems that can be modeled by functions. The English physicist, Isaac Newton, and the German mathematician, G. W. Leibniz, working independently, developed calculus during the 17th century.

How do you make x the subject of x squared-b equals 9?
x2-b = 9
x2 = 9+b
Square root both sides:
x = the square root of (9+b)
The clue is in the question inasmuch that there is no remainder so using the remainder theorem the result must equal zero:-
f(x) = x3+x2+xy+8
f(x) becomes f(1) because the divisor is x-1
f(1) = 13+12+1y+8 = 0 because ther's no remainder
f(1) = 1y = -10
So y = -10
What is the sum of all function in any circle graphs?
THere are infinitely many possible functions in any circle graph. Your question needs to be more specific.
Can you mail 3 sheets of 9 x 14 paper for 43?
It depends on:
- how large the sheets of paper are,
- which country you are posting from (units for 43, as well as postage rates),
- whether or not there are any postage deals or premium (express, insured, printed matter),
- where you are posting to (inland, abroad).
It is, therefore, not possible to answer the question with only the given information.
What is the volme of 752m x 319m x 110m?
Don't you have a calculator? Just multiply them together. It's really simple and a whole lot faster than going to a website and make us do your homework for you.
How much greater is 3x plus 2 than 5 7x?
(3x+2)-(5+7x) = 3x+2-5-7x = -4x-3
3x+2 is -4x-3 times greater than 5+7x.
Where is 3x raised to the 4th plus 4x raised to the 3rd -36x squared plus 1 increasing?
(3x)^4 +(4x)^3 -(36x)^2 +1 or 3x^4 + 4x^3 -36x^2 +1? Not sure from the way you said it.
In either case the method is the same. Use the power rule for differentiation, d/dx(x^n) = nx^(n-1), to take the derivative of the equation term by term, and then set this equal to zero and solve for x. You will get a cubic function when you do this, so you can try to factor it after you differentiate to simplify the problem.
Assuming the second case (It seems more likely) differentiating gives the following, which I have set equal to zero:
12x^3 + 12x^2 - 72x=0
x(12x^2 +12x-72)=0 Factor out an x
x(12)(x-2)(x+3)=0 Factor some more
This gives horizontal tangents at x=-3,0,and 2. Now all you have to do is plug some easy numbers into the derivative from the intervals between these values. Negative derivative means decreasing, positive means increasing. Good luck!
What is the value of the x in this equation 6 plus 6x56 x?
Unfortunately, limitations of the browser used by WA means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc.
What is the answer for x minus 3 over x plus two?
Solve? 2 is where the right piece of this function crosses the X axis, but the vertical asymptote is important here.
(X - 3)/(X + 2)
divide both terms, top and bottom by X
- 3/X divided by 2/X
same as
- 3/X * X/2
= - 3/2
========the vertical asymptote
What is the domain of the function xx-4 equals 4?
It is difficult to say because of uncertainty as to what xx-4 represents.
x2 - 4 = 4 gives x2 = 8 so x = ± 2*sqrt(2)
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. Also use ^ to indicate powers (eg x-squared = x^2).
How do you factor x to the power of b plus 1 minus x to the power of b?
It's hard to write this on a typewriter keyboard. Do you mean
xb + (1-x)b , or xb + 1 - xb , or maybe even x(b+1) - xb ?
The first cannot be factored.
The second equals 1, so it is already prime (cannot be factored).
The third could be written as xb(x) - xb(1), so there is a common factor of xb, and the expression can be factored as
xb(x-1). This is prime.
