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 divide 2x by x squared?
2x / (x2) = 2*x / (x*x); cancel an x from numerator & denominator: 2 / x
What does x stand for in 8x-4 equals 26?
8X - 4 = 26
add 4 to each side
8X - 4 + 4 = 26 + 4
8X = 30
divide each sides integers by 8
(8/8)X = 30/8
X = 30/8
===========reduces to
X = 15/4
--------------check in original equation
8(15/4) - 4 = 26
120/4 - 4 = 26
30 - 4 = 26
26 = 26
----------------checks
The answer is, X = 15/4 or 3.75
What is the answer to '-12-6x equals 12-10x'?
-12-6x=12-10x
we can add 12 to both sides, getting:
-6x=24-10x
then we can add 10x to both sides:
4x=24
divide both sides by 4:
x=6
the answer is x equals 6.
What are the solutions of x2 plus 7x plus 3 equals 0?
x2+7x+3 = 0
Using the quadratic equation formula the solutions are:-
x = -6.541381265 or x = -0.4586187349
Are 2 to the power of x and 2x the same?
No. 2x means 2 times x. For example, 210 = 1024, while 2 x 10 = 20.
How do you solve x plus 2y equals 4 y equals 2x plus 7?
x + 2y = 4 (A)
y = 2x + 7 (B)
2*(B) gives: 2y = 4x + 14
Substitute the right hand side for 2y in (A) to give: x + (4x + 14) = 4
Simplify: 5x + 14 = 4
Subtract 14 from both sides: 5x = -10
Divide both sides by 5: x = -2
Substitute for x in (B): y = 2*(-2) + 7 = -4 + 7 = 3
Solution: (x, y) = (-2, 3)
1 Angstom = 10-8 metres so 100 Angstrom = 10-6 metres = 1 micrometre or 1 micron.
What is 2xx minus 10x plus 8 factored?
2x2 - 10x + 8
2(x2 - 5x + 4)
2(X - 1)(X - 4)
==========zero factor rule
2(X - 1)
2X - 2 = 0
2X = 2
X = 1
=======agrees with above factoring
How do you answer -2x plus 6 less than equal to 4x plus 18?
-2x + 6 <= 4x + 18
-2x <= 4x + 12
-12 <= 6x
-2 <= x
Why does the period of a pendulum not depend on the amplitude?
Actually, the period of a pendulum does depend slightly on the amplitude. But at low amplitudes, it almost doesn't depend on the amplitude at all. This is related to the fact that in such a case, the restoring force - the force that pulls the pendulum back to its center position - is proportional to the displacement. That is, if the pendulum moves away further, the restoring force will also be greater.
From what I know it is equal to 1024 kbps. That's Kilobits per second not Kilobytes per second (KBps)
Solve X to the secont power -144 equals 0?
x^2-144=0
add 144 to both sides
x^2=144
take the square root of both sides
x=12
This is impossible to know with out two other numbers then you have to set ip a ratio. It's not very easy to explain you should ask someone in person to learn how to so it
