4. Edit bound={lower,upper}. lower and upper are the bounds
between which the TI-82 STATS searches for a solution. This is
optional, but it may help find the solution more quickly. The
default is
bound={L1å
åå
å99,1å
åå
å99}.
5. Move the cursor to the variable for which you want to solve
and press ƒ [
SOLVE] (above the Í key).
• The solution is displayed next to the variable for which
you solved. A solid square in the first column marks the
variable for which you solved and indicates that the
equation is balanced. An ellipsis shows that the value
continues beyond the screen.
Note: When a number continues beyond the screen, be sure
to press ~ to scroll to the end of the number to see whether it
ends with a negative or positive exponent. A very small
number may appear to be a large number until you scroll right
to see the exponent.
• The values of the variables are updated in memory.
•
leftNrt=diff is displayed in the last line of the editor. diff is
the difference between the left and right sides of the
equation. A solid square in the first column next to
leftNrt= indicates that the equation has been evaluated at
the new value of the variable for which you solved.
