Reference to Selected Keys on Scientific and Graphing
calculators
|
Keys or [FUNCTIONS] | Purpose(s) |
[=] or [ENTER] | Gives the result of the current operation. |
[yx] or [ab] or [ N ] | Raise any base to a power. For Example, 45
= 1024
4 [yx] 5 = 1024 |
[EXP] of EE] | Use to enter a number in scientific notation.
For Example, 6.1 x 108
6.1 [EXP] 8 |
[] or [(-)] | Changes the sign of the displayed number. Also use to enter a negative value. (This is not the substraction key.) |
[1/x] or [x-1] | Finds the reciprocal of a displayed number.
For Example, 0.25 [1/x] = 4 |
[STO] or [STO->] | Store a number in memory
For Example, Let w = 5 5 [STO->] [alpha] w [alpha] w [Enter] => 5 |
[RCL] or [2nd] [STO>] or [INV][STO] | Recalls a number stored in memory. May need to
press [2nd] [STO]
w [RCL] => 5 |
[x2] | Squares the displayed number.
For Example 2.1422 2.142 [x2] = 4.588164 |
[DEL] | On a graphing calculator, deletes previously entered characters. |
[x-VAR] or [x, r] or [x, r, ] or [x, r, , n] | On a graphing calculator, use to write the variable x. |
[y(x)=] or [y=] | On a graphing calculator, use
to enter equation(s) to be graphed.
For Example, y = 5 - 3x [GRAPH] [F1: y(x)=] y1=5 - 3 [x-VAR] |
[WIND] or [RANGE] or [WINDOW] | Ona graphing calculator, use to set the viewing
window to choose the part of the coordinate plane to be displayed.
Defaults are: xMin = -10, xMax = 10, xScl=1 ymin = -10, yMax = 10, yScl =1 |
[TRACE] | On a graphing calculator, use to find the x- and y-coordinates of points on a curve. |
[Graph] | On a graphing calculator, use to graph a previously entered equation(s) |
[2nd][TABLE] or [2nd][GRAPH] | On a graphing calculator, use for a table of values relating to an entered equation. The table can be used to estimate an answer to a problem. |
[OFF] or [2nd][OFF] | Turns calculator off |
