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.

What is the answer to 2X 3 9 X?
Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question.

What is the function for y equals x2?
f(x) = x2
This describes a parabolic curve, with it's vertex at the point (0, 0)
When can there be eight zeros in a billion?
One billion is 1000 million which is 1,000,000,000 although you can have one-hundred million which contains 8 zeros, 100,000,000.
What is the solution for the equation x plus 1 equals x plus 2?
x+1=x+2 x=1+2+x 0x=1+2 0x=3 0x=/=3 (=/= means does not equal) so there is no solution
What costs cannot be considered in calculating landed cost?
If your party is shipping you goods on an FOB incoterm, then the regular costs like import taxes, bank charges (wire-transfers), third party charges like an export trading company charges cannot be included. Operative word is FOB - Free on Board.
What hacks and extensions are added to MediaWiki to make WikiAnswers.com function as it does?
i believe it they didn't use any "hacks"; but think that it's actually just that mediawiki is porobably very customizeable.
5X plus 5y equals -7 how do you solve by elimination?
To solve for two unknowns (x and y) you need two independent equations.
All that you can do with the above is to express x in terms of y, as follows:
5x + 5y = -7
x + y = -7/5
x = -7/5 -y
Similarly, you could express y in terms of x as: y = -7/5 -x
IF, you had a value for either x or y from some other equation (or other source), you could substitute that value in either of these equations to solve for the other.
How do you solve -5x³ plus 3x²-8x plus 2 when x equals -2?
The given equation is,
-5x³ + 3x² - 8x + 2
Substituting the value of x in the above equation, we have
= -5(-2)³ + 3(-2)² - 8(-2) + 2
= 40 + 12 + 16 + 2
= 70
Hence on substituting the given value of x in the equation, the resultant answer is 70.
What are the applications of det of a matrix?
it is used to find the inverse of the matrix.
inverse(A)= (adj A)/ mod det A
Y equals -2x plus 6 what is the slope?
y=-2x+6
This is in slope-intercept form: y=mx+b
slope (m) = -2
Can two x minus one minus sin x equals 0 prove it only have one real root?
Let f(x) = 2x - 1 - sin(x)Then f(0) = -1 and f(1) = 0.1585
therefore, since f(x) is continuous, the change in sign shows that f(x) must have a root in the interval (0, 1).
Also f'(x) = 2 - cos(x).
therefore, since cos(x) <=1, f'(x) is always >= 1
That is, f'(x) is an increasing function of x.
Therefore there cannot be another root.
Three consecutive even integers are: 2x, 2x+2, and 2x+4.
I think the question says: 3(2x+4) = 2(2x) + 38
Eliminate parentheses:
6x + 12 = 4x + 38
Subtract 4x from each side:
2x + 12 = 38
Subtract 12 from each side:
2x = 26
2x+2 = 28
2x+4 = 30
=================================
Check:
Three times the greatest= 90
Twice the least = 52
90 exceeds 52 by 38 yay!
How do you find the sine cosine and tangent on a calculator?
If your calculator does not have sin, cos and tan buttons then you have a long task ahead.First, if the angle is measured in degrees, convert it to an angle measured in radians. To do this multiply the angle by pi and divide by 180.
Then
sin(x) = x - x^3/3! + x^5/5! - x^7/7! + ... where k! represents 1*2*3*...*k.
cos(x) = 1 - x^2/2! + x^4/4! - x^6/6! + ...
Keep going until the series converges.
tan(x) is most easily calculated as sin(x)/cos(x).
There really is no difference. Some people just say it differently.
Where to find Sword y in megaman 3 blue?
Sword Y chips are in green mysterydata in the ACDC and possibly Sci-Lab areas. If you trawl these areas long enough, jacking out and back in every time you finish a sweep, you'll find one eventually.
A*sin(x) + cos(x) = 1B*sin(x) - cos(x) = 1
Add the two equations: A*sin(x) + B*sin(x) = 2
(A+B)*sin(x) = 2
sin(x) = 2/(A+B)
x = arcsin{2/(A+B)}
That is the main solution. There may be others: depending on the range for x.
What does it mean when a variable is written x?
It doesn't make much difference which letter or letters you use as variables, so it doesn't really mean much.
∫ [1/[f(x)(f(x) ± g(x))]] dx = ±∫1/[f(x)g(x)] dx ± (-1)∫ [1/[g(x)(f(x) ± g(x))]] dx
