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 property of 3 x 0 equals 0?
It is called the zero property which says that any number into zero gives zero.
What is the solution set for 9x plus 2 equals x-5?
9x + 2 = x - 5
Subtract 'x' from each side of the equation:
8x + 2 = -5
Subtract 2 from each side:
8x = -7
Divide each side by 8 :
x = -7/8
The solution set is { -7/8 } .
What is the value of x if x 633?
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", "times", "equals".
There is no symbol between x and 633.
What is 1.59 as a fraction in simplest form?
To create a fraction in simplest form, we have to understand the intrinsic nature of a fraction:
Whole numbers in both the numerator and denominator
No factors shared in common between numerator and denominator
Knowing this, we can change 1.59 into:
1.59/1, but to satisfy the requirement of whole numbers:
159/100. This fraction can not be reduced any more, and is therefore your answer.
How do you find the rule of a function that doesn't have a relation between the x and y?

What is the easiest way to find area between two functions?
You have to integrate. There is usually no easy shortcut, except for some very simple functions.
When finding the area between to functions subtract the bottom function from the bottom function. Then integrate that from the starting to ending points. (If the functions switch which is on top and which is on the bottom over the interval you're integrating over, you'll have to split the problem into smaller problems around that point and add the areas together.)
What is the answer to 3x plus 9 equals 5x minus 4?
3x + 9 = 5x - 4
3x +13 = 5x
13 = 2x
13/2 = x
so x = 6.5
How would you prove that x plus 2 is a factor of the expression 2x cubed -3x squared -12x plus 4?
By (long) division:
. . . . . . . . . . .2x2 - 7x . + 2
. . . . . ----------------------
x + 2 | 2x3 - 3x2 - 12x + 4
. . . . . .2x3 + 4x2
. . . . . .-----------
. . . . . . . . . - 7x2 - 12x
. . . . . . . . . - 7x2 - 14x
. . . . . . . . . ------------
. . . . . . . . . . . . . . . . 2x + 4
. . . . . . . . . . . . . . . . 2x + 4
. . . . . . . . . . . . . . . . -------
. . . . . . . . . . . . . . . . . . . . .0
. . . . . . . . . . . . . . . . ====
(the "dot-spaces" are used to hold the characters in the right place of the division - they should be treated as blank)
Thus since
(x + 2)(2x2 - 7x + 2) = 2x3 - 3x2 - 12x + 4
(x + 2) is a factor of 2x3 - 3x2 - 12x + 4
In the division:
- the first term of the divisor (x) is compared with the highest power of x remaining in the dividend to find the next term of the quotient;
- the whole divisor is multiplied by this;
- then subtracted from the dividend;
- Steps 1-3 are repeated until there is no first term of the divisor (x) in the dividend.
- If the dividend is '0' (ie the last multiplication resulted in what was remaining in the dividend) then the divisor is a factor of the original dividend); otherwise it is not a factor.
What are the explanations of skew lines?
In plane geometry, two straight lines are either parallel (including coincident) or they meet at a point. In three dimensions, however, there is another option: the lines could be skew. These are lines that are not parallel but which do not intersect either. One way to visualise this is to place yourself in a cuboid room facing one wall. Consider the vertical line where the wall in front of you meets the wall to your left. And then consider the line where the floor meets the wall to your right. These two lines are not parallel but they will never meet. These are skew lines.
Can an object have zero velocity at the same time that it has acceleration?
Absolutely. That's exactly the situation of a rubber ball that was tossed straight up,
at the instant when it's at the top of its arc.
Any object that's not connected to anything else and is rising or falling has constant
acceleration ... the acceleration of gravity. If it was originally launched upward, then
it eventually runs out of steam, stops, reverses direction, and starts moving down.
At that instant during its constant acceleration, its velocity is zero.
What is the smallest staircase composite?
smallest staircase composite is the number 2222 because 1 is not counted as a prime so the 1 digit prime is 2, the smalles 2 digit prime is 11 and smallest 3 digit prime is 101. hope i helped =] P.S. you could have just checked it on the internet instead of asking. oh well XD
Math words with the letter v in it?
volume, vertical angles, vertexes, volume, vertices, and tht's pretty much all i know
(Cos30)300 = (0.883) 300 = 264.88 = 265 Nt.
What are the forces that act on an Internal hinge ex. x y or moment?

Your math is hard but your boyfriend is in the same math class should you drop or struggle threw?
If your boyfriend is in your math class but you're still having trouble, you should change class because things will probably get harder. If your boyfriend cared a lot about you, he wouldn't mind if you changed class.
9x+3y=-68
-2x+y=18
We are asked to solve with substitution so we first write y=18+2x.
Let us substitute this into the first equation.
9x+3(18+2x)=-68
9x+54+6x=-68
15x=-68-54=-122
so x=-122/15
and y =18+2(-122/15)==18+-244/15=270/15-244/15=26/15
So the solution is (-122/15,26/15) which is an ordered pair.
How do you solve this problem y equals x plus 9?
First, you have to be clear in your own mind of what the problem really is.
There is no problem here. There's only a statement, telling us the relationship
between two quantities, namely, that whatever one of them is, the other one
is bigger by 9.
Other than drawing a graph of this equation, there not a thing you can do with it.
There are an infinite number of pairs of numbers that 'x' and 'y' can be ... every point
on the graph is one of them.
Examples:
X . . . Y
0. . . . 9
1 . . . 10
2 . . . 11
9 . . . 18
42 . . 51
If you want to know a single number for 'x' and a single number for 'y', you need
another equation, in addition to the one given in the question.
