## How to Calculate and Solve for Linear Expansivity, Area Expansivity and Volume or Cubic Expansivity

Linear expansivity, area expansivity and volume or cubic expansivity are all parameters that are being governed by heat energy. All three parameter is dependent on temperature rise which is primarily in Celsius unit of temperature.

Linear expansivity additionally depends on the original length and final length, area expansivity additionally depends on the original area and final area and lastly, cubic or volume expansivity depends on the original volume and final volume.

The formula for calculating linear expansivity is (l2 – l1) / l1θ
l2 represents the final length.
l1 represents the original length.
θ represents the temperature rise in Celsius.

The formula for calculating area expansivity is (A2 – A1) / A1θ
A2 represents the final area.
A1 represents the original area.
θ represents the temperature rise in Celsius.

The formula for calculating volume or cubic expansivity is (V2 – V1) / V1θ
V2 represents the final volume.
V1 represents the original volume.
θ represents the temperature rise in Celsius.

## How to Calculate the Mechanical Advantage of a Machine (Physics)

Mechanical advantage is a very important parameter of machines and is considered a lever problem.

Nickzom Calculator – The Calculator Encyclopedia solves for mechanical advantage alongside a bunch of other problems in Physics.

For Example: Let’s calculate mechanical advantage of a machine when the load is 200 N and the effort is 120 N.

Effort = 120 N

Mechanical Advantage = 200 / 120 = 1.6667

Therefore, the mechanical advantage of the machine is 1.6667.

## How to Solve and Calculate the Mean or Average of Discrete and Continuous Numbers

Mean is a measure of central tendency and is considered to be a very important parameter of statistics. Mean or Average is the sum of the data sets or numbers or values divided by the number of numbers or data sets or values.

What is a discrete number?

A discrete number is a standalone number. It might be a whole number or fractional number but it stands on its own with no extension or range. An example of a discrete number is 5, 12, 10.6, 17, 20

What is a continuous number?

A continuous number is a range of numbers packaged as a single entity. An example of a continuous number is 5 – 10, 20 – 30, 25 – 50.

There are two possibilities in calculating the mean of a set of discrete numbers. One can either compute the mean via the application of frequency or no frequency at all.

For Example: A set of discrete numbers such as these:

4, 5, 6, 7, 8, 9

These numbers all occur once and have a frequency of 1 per number.

Therefore, if you want to create a table for the number and frequency, it looks like this:

Number        4, 5, 6, 7, 8, 9

Frequency    1, 1, 1, 1, 1, 1

You can clearly see that there is no need for applying frequency to calculate the mean of the above set of numbers. Application of frequency on a large set of numbers makes it easier to organize and compute the mean.

Now, for a set of numbers such as these:

4, 4, 4, 2, 4, 5, 3, 3, 3, 2, 1, 1, 6, 4, 3, 2, 4, 2, 5, 2, 1

You can see that some of the discrete numbers occur more than once and this implies that application of frequency is useful and makes the computing of mean easier and comprehensive.

From the display of numbers above you can see that the number 4 occurred times, the number 2 occurred times, the number 5 occurred 2 times, the number 3 occurred 4 times, the number 1 occurred 3 times, the number 6 occurred 1 time.

## How To Get Answers and Steps For a Function of a Function Differentiation (Calculus) Problem Using The Calculator Encyclopedia

According to Wikipedia,

In mathematicsdifferential calculus is a sub-field of calculus concerned with the study of the rates at which quantities change. It is one of the two traditional divisions of calculus, the other being integral calculus, the study of the area beneath a curve.

Nickzom Calculator calculates function of a function for the following formats:

• (expression)n
• k(expression)n
• sin(expression)
• ksin(expression)
• cos(expression)
• kcos(expression)
• tan(expression)
• ktan(expression)

## The Calculator Encyclopedia Converts Units of Illumination in Light Conversions

According to Wikipedia,

Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylightDaylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.

The calculator encyclopedia converts 12 units of illumination. These units are:

• Lux
• Meter-Candle
• Centimeter-Candle
• Foot-Candle
• Flame
• Phot
• Nox
• Lumen/sq. m
• Lumen/sq. cm
• Lumen/sq. ft
• Watt/sq. cm (at 555nm)

To commence this conversion, proceed to the Calculator Map, click on Light Switches under Switches (Unit Conversion).

## Nickzom Calculator Calculates Permutation and Combination With Steps – The Calculator Encyclopedia

According to Wikipedia,

In mathematics, the notion of permutation relates to the act of arranging all the members of a set into some sequence or order, or if the set is already ordered, rearranging (reordering) its elements, a process called permuting.

In mathematics, a combination is a selection of items from a collection, such that (unlike permutations) the order of selection does not matter.

Getting answers and workings (steps) for permutation and combination problems in Nickzom Calculator – The Calculator Encyclopedia is very simple and I would very much love to show you how you can do this easily.

You can access Nickzom Calculator (The Calculator Encyclopedia) via any of these channels:

First and Foremost, proceed to the Calculator Map, under the Mathematics section click on Permutation|Combination.

Let’s begin with solving a problem on Permutation. I hope by now you do know the value of n and r
