Input the values of the simplified 2 x 2 matrix you reduced earlier. Tab over to the menu on your display that reads “edit” using your calculator’s arrow keys. On a typical cross product calculator, you will press “2nd” and then the key whose second function says “matrix.” On the TI-Nspire, for example, this will require pressing “2nd” and then “x-1.” Your graphing calculator won’t be able to solve if you don’t reduce the vectors because your graphing calculator cannot solve for their variables.Īccess the matrix function on your calculator. While all cross product calculators will have slightly different ways of inputting vectors to find a cross product, finding the cross product on your calculator is generally simple:įirst, find the determinant of the two vectors and reduce them into 2 x 2 matrix form. How do I use my cross product calculator to find the cross product? Be sure that you fully understand these math concepts before plugging numbers into a calculator. In a high-level math course, much of your success will rely on being able to visualize vector concepts on your own and use these formulas on paper.

Although a cross product calculator is useful for quickly solving for the determinant in a cross product problem, it can’t set up these equations for you and also can’t tell you how to use these variables. Will a cross product calculator help me do better in my math class?Ī. The cross product of two vectors, a x b, is equal to a third vector, c, that is perpendicular (or orthogonal) to vectors a and b. Cross product calculator FAQ What is a cross product?Ī.
However, it’s also possible to perform operations on matrices on some scientific calculators, which cost as little as $45. Most cross product calculators are graphing calculators, which will cost you between $70 – $150.
How much you can expect to spend on a cross product calculator This is a great function to look for if you’re a serious math student, as it’s convenient and allows you to save graphs and other data to your computer. High-end cross product calculators often include a cable that allows you to connect your graphing calculator to the computer in order to manipulate graphs. Graphs with animated point plots, lists, spreadsheets and the ability to perform complex equations are nice features in a cross product calculator. Look for a cross product calculator that includes a range of functions you’ll find useful in your math studies. If you’re regularly performing advanced calculations, memory capabilities will allow you to save time by storing your most-used functions for long-term use. MemoryĬalculators with built-in memory can recall previously entered data such as functions and matrices. Middle-range calculators feature a basic LED display. High-end modern graphing calculators include backlit screens with bright colors and high resolution, which makes your calculator easy to read, even at night or after long study sessions. What to look for in a quality cross product calculator Display Standardized tests have their own calculator restrictions, which you must abide by in order to bring your calculator into the exam. Graphing calculators are ideal for higher-level courses, such as calculus and advanced algebra, but be sure your instructor allows them. If you’re buying your cross product calculator for a class, be sure to purchase one that aligns with your course requirements.

To learn more about the differences between scientific calculators and graphing calculators, check out the full graphing calculator buying guide from BestReviews. Some scientific calculators allow you to input matrices in order to perform calculations on vectors, which means you can use some scientific calculators as cross product calculators. Graphing calculators are powerful tools for creating graphs of functions and for performing a range of operations. In higher-level math courses, you’ll benefit from a cross product calculator that also serves as a graphing calculator to allow you to visualize the concepts graphically. What to know before you buy a cross product calculator Scientific vs. The Texas Instruments TI-Nspire CX II includes a built-in cross product function as well as a full-color display and an easy-to-navigate menu. The essential features of a cross product calculator are the ability to input 2D matrices and a function for finding the matrix determinant.
While it’s important to understand vector operations conceptually and graphically, a cross product calculator is a great supplemental tool for quickly finding the cross product of two vectors. In higher-level math courses, such as linear algebra and calculus, you’ll be required to find the dot product and cross product of vectors.
