| + | == Background and Identification == |
| + | |
| + | The TI-30X IIS is a scientific calculator originally released by Texas Instruments in 1993. It has an LCD screen above a grid of number and function buttons. The display has two rows: the top row—which is 10 digits wide—displays your equation as you type it while the bottom row displays the answer to your equation once you hit the “=” button. The top row will scroll left and right to accommodate an equation longer than 10 digits. |
| + | |
| + | As a scientific calculator, the TI-30X IIS supports most basic mathematical functions: arithmetic (addition, multiplication, subtraction, division), exponents, logarithms, and trigonometric functions (sine, cosine, tangent). It also has dedicated buttons for using constants like pi or squaring a number. |
| + | |
| + | The TI-30X IIS is mainly solar powered. The solar cell above the display is used to recharge a CR2025 lithium-ion battery inside the calculator. If the battery ever goes bad, you can use the [guide|37919|battery replacement guide] to unscrew the back and pop in a replacement. Many users, however, reported that their battery lasted quite a long time. Texas Instruments also produced the TI-30X IIB, which is almost identical but lacks the solar cell and is powered only by non-rechargeable batteries. |
| + | |
| + | You can identify this calculator easily by looking just above the display to find the Texas Instruments logo and the model number “TI-30X IIS.” The calculator comes in a variety of case colors such as black, red, pink, and blue. |
