How to use:

• To plot Log(sqrt([x])), enter:
  1. click sqrt
  2. click Log
• To plot sqrt([x]²+([x]+3)²),enter:
  1. click ^2
  2. shift to work window
  3. click +
  4. click 3
  5. click ()
  6. click ^2
  7. shift to main window and answer + to the query
  8. 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 [x]
5. click +
6. click 3
7. click )
8. click ^2
9. click sqrt

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

When you finish by clicking 'Plot It' you will be asked for the minimum and maximum value for x (the independent variable) and the minimum and maximum value for y (the dependent variable). If you don't know the later guess, that will not cause any problem. Enter numbers either as a regular number ,for example, 200 or in scientific notation in the form 2e+2.It may take awhile to generate the plot so be patient. Scroll down to find it.
