Using ESC Key

This blog post will act as a simple tutorial on how to use the ESC Key program.

Please see the bottom of this post to see what units to use in calculations.

Using the Library Formulae

The library system has been designed to be a simple to use interface.

The first step is to use the left hand drop down list to select the variable you want to calculate. For example if you need to calculate "Radius" you would select "Radius" from this list.

The second step is to use the second drop down list and look for the list that has all of the variables you have, for example if you wanted to calculate the "Radius" by using the "Area" you would selected "Radius" in the first drop down list and then select "Calculate using Area" in the second list.

From here you then need to fill in the values for the variables you have into the nput boxes that appear below the drop down boxes.

Once you have put in all your values either hit enter or press the "Calculate" button and ESC Key will calculate the answer for you!

All answers are put into the "History" tab with their formulas for later reference.

Using Your Own Formulae

To use your own formulae you firstly need to switch the tab from "Library" to "Non-Library". Once you have done this you will see six input boxes. The first being long placed at the top. This is the box you need to put the formula into. The formula needs to be enter in a specific way. This is that all the variables need to be renamed to be one of the following; "a1", "b1", "c1", "d1" or "e1", all different variables need to be renamed to a different new name.

Once you have done this you will notice that the five other input boxes have one of these new names in. Simply replace this with the value of that name. After this hit enter or click on the "Calculate" button and let ESC Key do the maths for you!

Once ESC Key has calculated an answer this will be displayed to you, as well as put into the "History Tab"

Using the Simultaneous Equation Solver

We have designed the Simultaneous Equation Solver to be simple to use.
The three input boxes are where you input the equations. These are located on the left hand side of the screen. If you are using two equations then leave the bottom box empty.

Input your equations using the following formats:

For two equations:
2X+4Y=50
Or
X+Y=5

For three equations:
2X+3Y-4Z=20
Or
X+Y+2Z=50
Or
0X+Y+3Z=80

Remember these four simple rules:

No Spaces
Always ensur all of the X's, Y's and Z's are there for three equations, X's and Y's for two equations.
The numbers, +'s and -'s can be changed
You must use X, Y and Z nothing else

Once you have entered all your equations either hit enter or click "Calculate"

For both two and three simultaneous equations this program uses Gaussian Elimination.

Units To Use

ESC Key uses standard metric formulas so uses standard metric units, below is a list of variables with the units to use;

Pressures:                          N/m^2 (Newtons per metre squared) or Pascals
Angles:                              ESC Key uses radians for all angle calculations
Accelerations:                   M/S (metres per second) for linear or Rad/S (radians per second) for angular
Energies:                           Joules
Lengths or measurments: Metres
Mass:                                 Kilograms
Weight:                              Newtons
Area:                                  Metres Squared
Volume:                            Metres Cubed
Resistance:                        Ohms
Current:                             Amps
Force:                                Newtons
Inductance:                        Henrys
Frequency:                         Herts
Stress:                                N/m^2 (Newtons per metre squared) or Pascals
Electrical Power:             Watts
