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 does x squared plus 16 t plus 47 cubed equal?
This equation has no meaning. 47 cubed is 103,823, but the rest of the equation is worthless without a value for x and t. At present, X and T do not have values, so you can not evaluate this expression.
How do you factor x squared plus four x?
You don't, if you're only looking for real number results. If you are including imaginary numbers, x2+4 = (x+2i)*(x-2i).
How do you determine a slope intercept equation?
Solve for y, getting the equation into the form of y = mx + b. m will then be the slope, and b will be the y intercept.
How many number of cubic meters are in a cubic millmeter?
1m = 1000 mm
1 cu m = 1m x 1m x 1m
= 1000mm x 1000mm x 1000mm
= 1,000,000,000 cu mm
=> 1 mm3 = 1/1000000000 m3
Take the derivative of the equation with respect to x:
dy/dx = d(x^2-2sin(x)+3)/dx
=d(x^2)/dx-2*d(sin(x))/dx+d(3)/dx
=2x-2*cos(x)
That's your tangent equation.
At x=0 ---> 2*0-2*cos(0) = -2
There's your slope.
What is parallel and skew line?
Parallel lines go the same way and are always the same distance from each other (eg you and a mate walking side by side).
Skew lines pass each other but don't meet, eg when you walk under a bridge and the train passes over. You are heading different ways, but you don't actually (just pass by)
X plus 3 plus 4x equals 13 so how much is x?
x + 3 + 4x = 13
3 +5x = 13 -- combine like terms
5x = 10 -- subtract 3
x = 2 --- divide by 5
"x" equals two
What is the value of a called in a linear equasion of y equals bx plus a?
This constant has the Y intercept value.
What is the meaining of E equals mc squared?
It means that there is a certain equivalence between matter and energy. For example, every amount of energy has an associated mass. c2 (the square of the speed of light) simply is the conversion factor. In SI units, that means that 1 joule of energy has an associated mass of 1 / (9 x 1018) kilograms.
How many thousandths of an inch are in 22 degrees at a diameter of 3.473?
First find the circumference, then multiply by 22/360 to get the arclength.
The circumference is pi time the diameter (or 2pi times the radius).
Pi times 3.473 is 10.9107512.
Multiplying that by 22, and dividing by 360 is .667 after rounding.
The answer is 667 thousandths.
What is the answer of this equation x y -1 and 4x y -10 using elimination method?
Do you mean: x+y = -1 and 4x+y = -10
If so then: x = -3 and y = 2
What is the value of the expression 6-2 - 5 - 8x when x -2 and y 5?
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).
There appears to be no y in the expression.
What is the solution k - 32 equals 16 - 2 plus 4?
k - 32 = 16 - 2 + 4
so k - 32 = 18
and then k = 18 + 32 = 50
If: 3x-5y = 16 then -5y = 16-3x => y = -3.2+0.6x by dividing all terme by -5
If: xy = 7 then x(-3.2+0.6x) = 7 => -3.2x+0.6x2 -7 = 0
Solving the quadratic equation: x = 7 or x = -5/3
Solutions of the equations by substitution are: x = 7, y = 1 and x = -5/3, y = -21/5
How to solve this If 20 give 85 And 30 give 75 Then 25 x X?
You cannot solve this without additional information. From what information is provided in the question you may not assume that the relationship is linear.
