The default guess is calculated as .
4. Edit
bound={lower,upper}. lower and upper are the bounds between which the TI-84 Plus
searches for a solution. This is optional, but it may help find the solution more quickly.
The default is
bound={L1â99,1â99}.
5. Move the cursor to the variable for which you want to solve and press ƒ\.
• 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
upper lower+()
