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 complete the square with the equation -1x 2 -5x plus 4?

-1x^2 - 5x - 25/4 = -25/4 - 4x^2 + 5x + 25/4 = 25/4 + 4

(x + 5/2)^2 = 41/4

What is the name of a shape with 207 sides?

Most scientists would call it a 207-gon, but you could use dihectakaiheptagon

3.5 inches equals CM?

The answer is 8.89 cm (approx.). Inches and centimeters are both units of linear measurement. Inches are used in the imperial system whereas centimeters are used in the metric system. To convert from inches to cm, multiply the inch unit by 2.54.


To convert from inches to centimeters, multiply by 2.54.

How do you find the x-intercept of y equals 1 over 2x minus 2?

You let y=0 (sub this into the equation), then work out what x equals. i.e 0=1/(2x)-2 becomes 2=1/(2x) etc...

What is the Line of symmetry of x squared plus 8x minus 20 equals 0?

x = -4

The equation to find this is -b/2a with 8 being the b and 1 being the a.

How do you solve the problem 0.25m plus 3 4?

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.

Something seems to be missing between 3 and 4 at the end of the question.

What is the uses of maths in secondary level?

The answer depends on secondary level of WHAT! Please edit the question to include more context or relevant information.

Given y plus 6y' plus 13 y equals 0. How do you find the frequency of the oscillation and describe the motion as t to infinity?

well, simplifying:

6y'+14y=0

Take y=c*e^(rt), substitute and divide by c*e^(rt):

6r+14=0, r=-7/3

y=c*e^(-7t/3), no oscillation occurs.

However, if you meant y''+6y'+13y=0,

Use the same methods:

r^2+6r+13=0

Solving, r=-3 plus or minus 2i

substituting r and using superposition principle.

y=(e^(-3t))(c_1cos(4t)+c_2sin(4t))

Frequency is probably period which is 2pi/4=pi/2, and taking the limit as t approaches infinity e^(-3t) is zero so the sine and cosine terms don't matter. So y approaches zero as t approaches infinity.

What is 21 minus 5X divided by 2 10X plus 6 divided by 3?

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", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y) 2.

There is, for example, no operator between 2 and 10X.
