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.

If y varies inversely as the square of x and y equals 4 when x equals 3 find y when x is 2?

The statement "y varies inversely as the square of x" means that in function form y(x) = k/x2, where k is an (initially) unknown constant. The second condition can be written in algebraic form as 4 = k/32 ; or k = 4 X 9 = 36; Then y(2) = 36/22 = 9.

Antiderivative of x cubed divided by 3?

x4/12 since derivative of x4/12 is 4x3/12 or x3/3

What is calculas?

It is a branch of maths that involves Calculating rates of change and irregular.curved volumes.

'The word 'Calculus' is Latin and means 'stones'. Where the ancients would have used stones/pebbles to make calculations.

Is 76 composite or prime?

Composite, because it can be divided by '2'.

NB All even numbers , except '2', are composite, therefore NOT prime.

All prime numbers are odd number, except '2'. However, not all odd numbers are prime numbers.

All EVEN numbers end in 0,2,4,6,8

All ODD numbers end in 1,3,5,7,9.

Since '76' ends in '6' , then it is an even number, hence composite.

How do you solve 64x2-5 equals 11?

64x^(2) - 5 = 11

Equate to zero , by subtracting '11' from both sides.

Hence

64x^(2) - 16 = 0

Algebraically rearrange

(8x)^(2) - 4^(2) = 0

We now have two squared terms with a negative between them. This factors to :-

(8x - 4)(8x + 4) = 0 Note the different signs in each brackets.

Hence

8x - 4 = 0

8x = 4

x - 4/8

x = 1/2

&

8x + 4 = 0

8x = -4

x = -4/8

x = -1/2

So the two solutions are x = 1/2 & x = -1/2

NB Twosquared terms with a POSITIVE(+) between them , does NOT factor.

What does 8x for each value of x mean?

The expression "8x for each value of x" means that you are multiplying the value of x by 8. This indicates that for every possible value of x, you will multiply that value by 8. For example, if x is 2, then 8 multiplied by 2 equals 16. This expression represents a linear relationship where the output is 8 times the input value of x.

What is the best textbook for learning advanced calculus?

One highly recommended textbook for learning advanced calculus is "Advanced Calculus" by Gerald B. Folland.

How are surds used in real life?

They are not something most of us would use in ordinary daily activities like shopping and bank statements, but like all mathematical topics they will crop up somewhere at some time in the normal, real-life work of mathematicians, scientists and engineers.

What is 56 x 6 equals?

Oh, dude, math time! So, like, 56 times 6 equals 336. Boom, there you go. Math wizardry at its finest.

How do you find the radius of a cylinder when height and volume are given?

The volume of a cylinder is given by the equation V=2*pi*r*h

V=volume

r=radius

h=height

Since the height and volume are given in this case, rearranging the equation will show that r= V / (2*pi*h). With that equation you can find the radius of any cylinder with known volume and height.

What is 20 x 0?

Well, isn't that a happy little question! When you multiply 20 by 0, you get 0. It's like having 20 friends over for a painting party, but if no one shows up, you still have a peaceful time painting by yourself.

What is the shape and bond angles of molecule x-y-x?

Oh, dude, molecule x-y-x has a linear shape with bond angles of 180 degrees. It's like a straight line, you know? So, if you're ever in a geometry competition and they ask about x-y-x, just remember it's as straight as a ruler.

Factor x cubed plus 5x squared plus 6x?

To factor the expression x^3 + 5x^2 + 6x, we first look for common factors among the terms, which is x. Factoring out x gives us x(x^2 + 5x + 6). Next, we factor the quadratic expression x^2 + 5x + 6 by finding two numbers that multiply to 6 and add up to 5, which are 2 and 3. Therefore, the factored form of x^3 + 5x^2 + 6x is x(x + 2)(x + 3).

What does c equal?

In math, a number signified by "C" is a constant number. A constant is the opposite of a variable. While a variable changes, a constant will always stay the same.

For example, in the equation y = 4x + 10, 10 is a constant. If you did not know the value of 10 (for example, if you had just integrated), it could be written as y = 4x + c.

Write 175000000 in words?

One hundred and seventy-five million.

What is the highest number ever counted to?

It appears there are no records of the highest number ever counted to. Because of that, it would be impossible to say what the highest number ever counted to is and any claims (see below) would be unverifiable. If you counted one integer per second every second for sixty years, you wouldn't make it to two billion, so let's say the record is less than that.

One experience:

I recently counted to "approximately" 258 quintillion googol.

What does x to the half power mean?

Ah, a half power is like giving x a gentle hug and telling it to take a deep breath. It means finding the square root of x, which is like finding the number that, when multiplied by itself, equals x. So, x to the half power is just a way of saying the square root of x, allowing us to simplify and understand things in a beautiful way.

How do you multiply 2x by 2y?

suppose u have a(x) and b(y)where a and b are constants , Multiplying a(x) by b(y) it's simply ab(xy) So if u have 2x by 2y this equals to 4xy

or

The answer is 4xy.

2x = 2 times x

2y = 2 times y

2 times x times 2 times y = 2 times 2 times x times y = 4xy

What is p x 5 x r?

5pr.

The specific answer depends on the values of the variables p & r.

Is x to the power of 2 the same as x squared?

Oh, absolutely! When we talk about x to the power of 2, we're simply saying x multiplied by itself, which is the same as x squared. It's like painting a beautiful little tree with just a few brushstrokes - different ways of saying the same thing, but all leading to a lovely result.

What is 5c x 100 equals?

To calculate 5c x 100, you would first convert the percentage to a decimal by dividing by 100, which gives you 0.05. Then, you would multiply 0.05 by 100, resulting in 5. Therefore, 5c x 100 equals 5.
