[. . . ] Examples assume all default settings, as shown in the Modes section. For more activities and examples, see the ATE 7 MultiView Teacher Guide available at education. ti. com/guides. Switching the ATE 7 MultiView calculator on and off & turns on the ATE 7 MultiView calculator. The display is cleared, but the history, settings, and memory are retained. The APD™ (Automatic Power Down™) feature turns off the ATE 7 MultiView calculator automatically if no key is pressed for about 5 minutes. [. . . ] You can also convert between rectangular coordinate form (R) and polar coordinate form (P). Choose an angle mode from the mode screen. You can choose from DEG (default) or RAD. Entries are interpreted and results displayed according to the angle mode setting without needing to enter an angle unit modifier. If you specify an angle unit modifier from the Angle menu, the calculation is performed in that angle type, but the result will be given in the angle mode setting.

He estimates that he will need to earn $240 to buy everything he would like to have. Create a table of Harry's weekly earnings to see how his savings will grow. How many weeks will Harry need to work to save enough money for his purchases?%n (Press - if necessary to clear a previous operation. ) T 15 < 0 mmmm mmmm mmmm mmmm 29 The table of values of Harry's weekly earnings is shown on the screens. From this table, we can read that Harry will have to work 16 weeks to earn $240. Memory and stored variables z L %h %{ The ATE 7 MultiView™ calculator has 7 memory variables—x, y, z, t, a, b, and c. You can store a real number or an expression that results in a real number to a memory variable. Press L to store a variable, and press z to select the variable to store. Press < to store the value in the selected variable. If this variable already has a value, that value is replaced by the new one. Press this key multiple times to choose x, y, z, t, a, b, or c. You can also use z to recall the stored values for these variables. [. . . ] LOW BATTERY — Replace the battery. Note: This message displays briefly and then disappears. Pressing - does not clear this message. Battery information Battery precautions • Do not leave batteries within the reach of children. • Do not mix new and used batteries. [. . . ]
