Texas Instruments TI-36X Pro Scientific Calculator Guidebook

Advanced, four-line scientific calculator, with higher-level math and science functionality, is ideal for computer science and engineering courses in which graphing technology may not be permitted.


Each section is followed by instructions for keystroke examples that demonstrate the TI-36X Pro functions.

Examples assume all default settings, as shown in the Modes section.

Some screen elements may differ from those shown in this document.

Home screen

On the Home screen, you can enter mathematical expressions and functions, along with other instructions. The answers are displayed on the Home screen. The TI-36X Pro screen can display a maximum of four lines with a maximum of 16 characters per line. For entries and expressions of more than 16 characters, you can scroll left and right to view the entire entry or expression.


You can also convert between rectangular coordinate form (R) and polar coordinate form (P). (See Rectangular to polar for more information.)

Choose an angle mode from the mode screen. You can choose from DEG (default), RAD, or GRAD. Entries are interpreted and results displayed according to the angle mode setting without needing to enter an angle unit modifier.


Pressing one of these multi-tap keys repeatedly lets you access the corresponding hyperbolic or inverse hyperbolic function. Angle modes do not affect hyperbolic calculations.

Memory and stored variables

The TI-36X Pro calculator has 8 memory variables – x, y, z, t, a, b, c, and d. You can store a real or complex number or an expression result to a memory variable. Features of the calculator that use variables (such as the solvers) will use the values that you store.
