The generated code should work as desired. However, it is not as efficient as possible. For example, it overuses eval() (which evaluates an expression as a number, if possible) and parseFloat() (which converts a string to a number when possible). This should not cause a problem.

MyTestAssistant© allows up to 26 variables this tool will create solutions with up to 7 variables.

This requires Netscape 4.0 or Internet Explorer 4.0 for full functionality.

How to use:

• To generate the code to calculate Log(sqrt([x])), enter:
  1. click sqrt
  2. click Log
• To generate the code to calculate sqrt([x]²+([y]+3)²),enter:
  1. click ^2
  2. shift to work window
  3. click clr (Note: On a Mac NN4+ fails to clear due to a 'bug'. Do so manually)
  4. click [y]
  5. click +
  6. click 3
  7. click ()
  8. click ^2
  9. shift to main window and answer + to the query
  10. click sqrt

The reason the second window is necessary is when a function is called it is assumed that it is applied to everything in the current window. Thus

1. click ^2
2. click +
3. click (
4. click [y]
5. click +
6. click 3
7. click )
8. click ^2
9. click sqrt

would produce
sqrt(([x]²+([y]+3))²)

instead of

sqrt([x]²+([y]+3)²)

By using the auxiliary window repeatedly you can, add, subtract, multiply, or divide any number of functions. Thus

sqrt([x]²+([x]+3)²-([y]-5)²)
is just as easily managed. Very complex functions can be generated in this manner.

There is now a conditional allowed for the variable [x], but not for [y], it is in the form of

if [x]<comparator>Number->DoThis - otherwise - Do This.

The allowed <comparators> are:

< - Less Than

<= - Less Than Or Equal To

> - Greater Than

>= - Greater Than or Equal To

== - Equal To

!= - Not Equal To

If you are going to use this feature you must use it first after selecting the problem number.

• To do so click the IF button, you will be asked to choose a comparator and then a number to compare [x] to. This can be a fixed number or any of the other variable [t]-[z].
• Next author the formula you wish to use if the condition is satisfied.
• When you finish press the ELSE button. The formula you authored should be cleared (but not on a Mac with Netscape 4+ - see note above) and you should then enter the formula for the result if the condition is not satisfied.
• Press the EndIf button and then the Done button and you are finished.

When you finish by clicking 'Done' you will be given the chance to enter a numerical value for [x] and [y] if you used it and any other variable you used, which will allow you to check your formula.
