In this article (and video above), I talk about a tool that can make a significant difference in your exam performance – the TI-36X Pro calculator. Often overlooked, this calculator is a powerhouse of functionality and can be your best ally during the FE Exam.
From solving complex equations to effortlessly managing matrices and vectors, this calculator is more than a tool – it’s your ally in the rigorous test of knowledge and time management that is the FE Exam. Let’s look at some of its features that will help you during the FE Exam:
Equation Solver:
The equation solver feature of the TI-36X Pro. This is not just a basic tool; it’s a game-changer for solving a wide range of equations. When you encounter linear, quadratic, cubic, or quartic equations, this feature can drastically reduce the time spent on calculations. You can access this solver by pressing |2nd| → num-solv. Here’s a time saving tip: you can input a guess value for the variable that’s close to the actual answer. This speeds up the calculator’s processing time, ensuring that you move through questions more efficiently.
Stacked Fraction View:
Next, we have the stacked fraction view. This is especially useful for visual learners. When dealing with complex fractions, it’s easy to lose track of your calculation. The stacked view displays fractions exactly as you would write them by hand, reducing the risk of errors. To use this feature, simply press the key above number 7. This view is particularly helpful for long equations or when dealing with multiple fractions.
Store Values in Variables:
Moving on to storing values in variables. The FE Exam often requires multi-step problem-solving. Instead of re-calculating values or writing them down, you can store them in the calculator. For example, if you calculate a part of the problem and know you’ll need that number later, just store it in a variable like A, B, or C. This not only saves time but also reduces the chance of making errors in re-entering data. To recall your last calculation without having to store it, use |2nd| → |answer|.
Solve Derivatives and Integrals:
The TI-36X Pro’s capability to solve derivatives and integrals is a boon for those dealing with calculus-based problems. This feature can be vital in solving optimization problems, determining areas under curves, and more. To access this, press |2nd| followed by the integral or derivative key. While these calculations can be complex, the TI-36X Pro simplifies the process, allowing you to focus on the application of these concepts rather than the nitty-gritty of computation.
Solve Matrices:
Matrix operations are another advanced feature of the TI-36X Pro. Whether you’re solving systems of equations or working with multiple variables, matrix functions can be incredibly helpful. To start working with matrices, use the sequence |2nd| |matrix|. You’ll be able to create and edit matrices, and perform a variety of calculations with them. While matrices may not be a central part of every FE Exam, understanding how to use this feature can save you significant time on certain problems.
Solve Vector Problems:
Vector calculations are integral in fields like mechanical and civil engineering. The TI-36X Pro simplifies vector problems significantly. You can access vector functions by pressing |2nd| |vector|. Here, you can input vectors, perform calculations like dot products, cross products, and more. This is particularly useful for visualizing and solving problems in physics and engineering that involve forces, velocities, and other vector quantities.
Convert Units:
Unit conversions can be tricky and time-consuming, but with the TI-36X Pro, they become effortless. Whether you’re converting between metric and imperial units or dealing with temperature, weight, or volume, the calculator’s unit conversion feature is extremely useful. This is particularly helpful in ensuring that all your units are consistent, thereby avoiding common errors in calculations.
Statistics Functions:
The TI-36X Pro is also well-equipped for statistical analysis. It can calculate mean, median, standard deviation, and more. For those dealing with data analysis or statistical components in the FE Exam, this feature is invaluable. It allows for quick, accurate calculations, ensuring that your data interpretation is as precise as possible.
Complex Number Operations:
The TI-36X Pro offers straightforward operations for complex numbers, including addition, subtraction, multiplication, and division. This feature allows for efficient and error-free calculations involving complex numbers, which can be a common occurrence in certain engineering fields.
Bonus Tips:
- Practice is crucial. Spend time getting to know your TI-36X Pro. The more familiar you are with its functions, the more efficient you’ll be during the exam.
- Always read the specific instructions for each section of the FE Exam regarding the use of calculators.
- Be strategic with your calculator use. While it’s a powerful tool, not every problem requires its use. Sometimes, simpler methods or mental math can be quicker.
- Double-checking your work is essential, especially when using the calculator’s more advanced features. This helps catch any potential errors and ensures
We’ve covered some of the most powerful features and tips for the TI-36X Pro calculator, giving you the know-how to tackle the FE Exam with confidence and efficiency. Remember, the key to mastery is practice. So, grab your calculator and start exploring these features. Each minute you spend familiarizing yourself with the TI-36X Pro is an investment in your exam success.
