things you can do on the ti-36x pro calculator Formula

While the TI-36X Pro is a physical scientific calculator, one of the most powerful things you can do on it is utilize the “Num-Solv” feature to handle multi-variable equations. This tool replicates that logic for the standard Break-Even equation:

P × Q = F + (V × Q)

Where Revenue equals Total Costs.

Variables

• Fixed Cost (F): Costs that remain constant regardless of production volume (e.g., rent, insurance).
• Variable Cost (V): Costs that vary directly with the level of production (e.g., materials, labor per unit).
• Price (P): The selling price per individual unit.
• Quantity (Q): The number of units required to break even (profit = 0).

What is things you can do on the ti-36x pro calculator?

The phrase “things you can do on the ti-36x pro calculator” refers to the extensive capabilities of this advanced scientific calculator, which bridges the gap between standard scientific models and graphing calculators. It is widely used by engineering students, computer science majors, and business professionals.

Unlike basic calculators, the TI-36X Pro allows users to scroll through history, perform vector and matrix arithmetic, and most importantly, solve for unknown variables in linear equations. This web module specifically simulates the linear equation solver capability used for financial Break-Even Analysis, a common requirement in engineering economics exams.

How to Calculate things you can do on the ti-36x pro calculator (Example)

Suppose you are using the calculator to determine how many units (Q) you must sell to cover your costs. Here is the step-by-step logic the calculator performs:

1. Identify Knowns: Fixed Costs ($F$) = $1,000, Variable Cost ($V$) = $10, Price ($P$) = $20.
2. Set up the Equation: $Total Revenue = Total Costs$, or $20Q = 1000 + 10Q$.
3. Isolate the Unknown ($Q$): Subtract $10Q$ from both sides to get $10Q = 1000$.
4. Solve: Divide by 10. $Q = 100$. You need to sell 100 units.

Frequently Asked Questions (FAQ)

Can the TI-36X Pro solve for X in any equation?

Yes, utilizing the “num-solv” feature, you can enter an equation with one unknown variable, and the calculator will iterate to find the value of X.

Is this calculator suitable for the FE Exam?

Absolutely. The TI-36X Pro is one of the few advanced calculators permitted for use on the NCEES Fundamentals of Engineering (FE) exam.

How does this web tool differ from the physical calculator?

This web module solves specifically for the linear Break-Even variables instantly, whereas the physical calculator requires you to manually input the equation syntax first.

What happens if the denominator is zero?

If the Price equals the Variable Cost ($P – V = 0$), the calculator will return an error, as you can never cover fixed costs if you make no profit per unit.
