Mathematical & Scientific Functionality of the TI-36X Pro

Categorized Mathematical Functions

Basic Arithmetic
The calculator supports fundamental operations with precision, including fractional arithmetic, percentage calculations, and memory functions. These operations form the foundation for more complex computations.

• Standard Operations: Addition, subtraction, multiplication, and division follow standard syntax (e.g., 5 × 3 + 2 = 17). The calculator adheres to the order of operations (PEMDAS/BODMAS).
• Fractional Arithmetic: Input fractions directly (e.g., 3 1/2 + 2 3/4) or convert decimals to fractions (e.g., 0.75 → 3/4 via the →Frac function).
• Percentage Calculations: Compute percentages using the % key (e.g., 20 % of 150 → 150 × 20 % = 30). Reverse operations (e.g., finding the base or rate) are supported via 1/x and algebraic manipulation.
• Memory Functions: Store and recall values using STO→ and RCL (e.g., STO→ A 5, then RCL A × 2). Multiple memory registers (A–F) are available.

• Exponents and Roots: Compute powers (x^y) and roots (√x, y√x) directly (e.g., 2^8 = 256, ∛8 = 2).
• Solving Equations:

  Quadratic equations are solved using the EQN function (e.g., for ax² + bx + c = 0, input coefficients, then select SOLVE).
  Example keystrokes:
  1 [ALPHA] [EQN] 2 [ALPHA] [EQN] -3 [ALPHA] [EQN] SOLVE Outputs roots x = 1 and x = 3.

• Factoring: Factor polynomials via the FACT function (e.g., x² - 5x + 6 → (x-2)(x-3)).
• Logarithms and Exponentials: Natural (ln) and base-10 (log) logarithms, along with e^x and 10^x, are accessible via dedicated keys.

• Descriptive Statistics: Compute mean (x̄), variance (σ²), and standard deviation (σ) for one-variable data sets using STAT mode. Example:

  Input data: 2, 4, 6, 8 → STAT → 1-VAR → x̄ = 5.

• Regression Analysis: Perform linear (y = mx + b) and exponential regression via STAT → REG. The calculator provides slope, intercept, and correlation coefficient (r).
• Probability Distributions: Calculate probabilities for binomial, normal, and Poisson distributions using DISTR (e.g., P(X ≤ 2) for Binomial(n=5, p=0.3)).
• Hypothesis Testing: Conduct t-tests and z-tests for means via STAT → TESTS, with options for one-sample, two-sample, and paired tests.

• Primary Functions: Compute sine (sin), cosine (cos), and tangent (tan) (e.g., sin(30°) = 0.5). Mode selection (DRG) toggles between degrees/radians/gradients.
• Inverse Functions: Calculate angles using sin⁻¹, cos⁻¹, and tan⁻¹ (e.g., tan⁻¹(1) = 45°).
• Hyperbolic Functions: Access sinh, cosh, and tanh via 2nd [TRIG].

• Scientific Notation: Input/output values in E notation (e.g., 6.022 × 10²³ for Avogadro’s number).
• Unit Conversions: Convert between 200+ units (e.g., meters to feet, Celsius to Fahrenheit) via UNIT (e.g., 25 °C → 77 °F).
• Complex Numbers: Perform operations with complex numbers (e.g., (3+4i) + (1-2i) = 4+2i) using a + bi syntax.

Step-by-Step Complex Calculations

Solving Quadratic Equations
To solve 3x² - 5x + 2 = 0:

1. Press 3 [ALPHA] [EQN] -5 [ALPHA] [EQN] 2 [ALPHA] [EQN] to input coefficients.
2. Select SOLVE from the EQN menu.
3. The calculator returns roots: x ≈ 2 and x ≈ 1/3.

1. Enter matrix A via MAT → EDIT → [A], input rows.
2. Repeat for matrix B.
3. Multiply via MAT → [A] × [B] to yield [[19,2

Physics Problem-Solving for High School Students: Projectile Motion

The TI-36X Pro simplifies multi-step physics problems by automating repetitive calculations and organizing data logically. Below is a step-by-step scenario where a student calculates the trajectory of a projectile launched at an angle, including annotated screen captures (described for clarity).

Scenario: A ball is launched from ground level with an initial velocity of 20 m/s at a 30° angle. Determine:
1. Maximum height reached.
2. Horizontal range.
3. Time of flight.

Step-by-Step Solution with TI-36X Pro:
1. Convert Angle to Radians:


60. Input: `30` → `SHIFT` → `DRG` (Degree Mode) → `ENTER` → `SHIFT` → `→R` (Convert to Radians).
61. Display: `0.5236` (30° in radians).

2. Calculate Vertical and Horizontal Velocity Components:


62. Vertical velocity (`v_y`): `20 SIN(0.5236)` → `SHIFT` → `SIN` → `ENTER` → `×` → `20` → `ENTER` → `=` → Display: 10 m/s.
63. Horizontal velocity (`v_x`): `20 COS(0.5236)` → `SHIFT` → `COS` → `ENTER` → `×` → `20` → `ENTER` → `=` → Display: 17.32 m/s.

3. Compute Time to Reach Maximum Height:


64. Use `v = u + at` (where `v = 0` at peak, `a = -9.81 m/s²`).
65. Input: `0 - 10` → `/` → `-9.81` → `ENTER` → `=` → Display: 1.02 s.

4. Calculate Maximum Height:


66. Use `s = ut + 0.5at²` with `t = 1.02 s`.
67. Input: `10 1.02` → `+` → `0.5 -9.81 (1.02)^2` → `SHIFT` → `x²` → `ENTER` → `×` → `-9.81` → `ENTER` → `×` → `0.5` → `ENTER` → `+` → `=` → Display: 5.1 m.

5. Determine Total Time of Flight:


68. Double the time to peak: `1.02 2` → Display: 2.04 s.

6. Compute Horizontal Range:


69. Use `range = v_x total time`.
70. Input: `17.32 2.04` → Display: 35.3 m.
