- User-defined variable cannot be used in the Quick Calculator but functions such as  fac(),
log(), ln(),
  sin(), cos(), tan(), arcsin(), arccos()
and arctan() are available. In case of using the trigonometric   functions, choose either Degrees, Radians or Gradients.
- Quick Calculator returns the result when you press "=" button and
Unit Converter returns the result
  when you press ¡°

- There is no specific sequence in preparing the formula calculator but users are recommended to set    the paths of figures for formula description at the last step for convenience. Contents to be filled and    functions of each button are as follows;

   1) Select Category1 and Category2. 
   2) Formula name : Name the formula calculator you want to create.
   3)
Writing the formula (in an equation form)
      
The formula does not necessarily begin with ¡°y=¡± and users can adopt any variable. However, the       equal sign(=) must be inserted.
      Clicking the ¡°Select built-in function¡± button, users can use several built-in functions.       Trigonometric functions (sin, cos, tan, arcsin, arccos, arctan) logarithmic functions (log, ln)       and factorial (fac) are available.
      Users can define variables but built-in functions are unavailable for defining the variables.
      Name of a variable
must not begin with a number. Ten user-defined variables at maximum
      are allowed.
      
If any of trigonometric functions (sin, cos, tan, arcsin, arccos, arctan) are used in the formula,       users must select either one of unit of degree among ¡°Deg¡±, ¡°Rad¡± and ¡°Gra¡±.
   4) Once the formula is written, check/reset the unit and click the
¡°Click, to find the variables in         Formula¡± button.
   5) Clicking the ¡°Click, to find the variables in Formula¡± button will search in the written formula
        and list user-defined variables.
   6) Fill the initial/default value and description for each variable.
   7) Clicking the ¡°
Click, to calculate¡± button will show the calculation result.
   8) Figures or diagrams for formula and description can be inserted by selecting the path.

   9) Add the description and references for the formula.
 10) Click the ¡°

-
In the ¡°My Page¡± menu, users can modify or delete their own formula calculators or make them  
  open to public.
 
-
After creating a formula calculator by the ¡°Write a Formula¡± menu, the created formula calculator is   registered to the user¡¯s ¡°My Page¡± with its default status being ¡°private¡± in which   the creator only
  can view it.
 
-
If a formula calculator is open to public, all users including non-registered ones can use it and make   search for it by selecting categories and/or keywords searching.
