When students are first able to purchase a graphing calculator for class, they are often excited because they think it will make their work much easier. A calculator such as the TI 90 Platinum graphic calculator can be a lifesaver for a student who knows how to use it properly. However, there are a few issues that may come up and make it quite confusing if students do not know with what they are dealing. There are many times when a student uses their calculator to graph an equation and something just looks funny about the graph. In most cases, this is because they do not have the window set properly for the graph. They can use the F1 and F2 keys on their calculator to set the window properly for their equation. A common error that students encounter when they are using their calculator is the Error 12: DIM MISMATCH message. This means that they have the statistical plot on but have not entered any value to graph. To get rid of this error message, all they need to do is turn the plot off. This calculator can be complicated but it also has features that make the student's life much easier if they know how to use them. They should not forget about the storage area that is available in their calculator. This allows students to edit and check equations and liens without having to reenter them. When a student gets a TI 89 Platinum graphing calculator, they may be overwhelmed by all of the things that it can do and everything that can go wrong. However, if they take the time to learn how to use it properly, they will see how helpful it can be. Understanding common error messages and how to fix them will save a lot of trouble for math students.
