SciPlus-3300 Scientific Calculator – User Guide
At any time, you can query a variable by simply selecting the key without a value or expression
after the variable. For example,
a=
will display “3” in the results line. If you have not yet entered
a value for a, then “a=undefined” will be displayed in the results line.
You can always over write any variable with a new value.
4.
What’s the answer?
Once all four variables have been entered, you can select
y=
to show the
result. The value of y = 3x
2
+ 2x + TAN(45) for the value of x=3 in the middle line (“34” in this example
as shown).
If the equation contains a divide by zero condition, the result Y=DIV0 will be displayed.
If you see “y=…” in the middle line, it means that not all of the necessary variables have been entered
yet. Zero values must be entered as such.
5.
Changing variables:
At any point, you can change one of the values of a, b, c, x by repeating step ‘3’
above. A new value of y will be calculated each time a variable is entered.
For example, to find the value of y=ax
2
+bx+c for a new value of x=4, simply enter
x= 4
.
6.
Editing the equation:
To edit the equation, use
y
è
to put the equation into the input line. Move
the cursor to the location you wish to edit. Remember removes operators from the equation.
7.
Entering a new equation:
You can easily enter a new equation by repeating step 2 above. The values
for a, b, c, x will remain unchanged until you change them as explained in step 3.
8.
Clearing everything:
You can use
CLR
to clear all the constants as well as the equation and start
fresh.
