I was doing a statistics probability problem and I needed to find the value of (0.17)4. I'm taking an online "Elementary Algebra" class from my local community college. When I entered the value into my calculator, I noticed that it gave me the answer in scientific notation (8.3521E-4). ![]() I figured let me try entering 8.3521 10-4 hoping that it'd give me the decimal form I was looking for. It's been a few years since I graduated high school and I've forgotten pretty much everything including my T-84 Silver, which I never took full advantage of its potential anyway. So I went out and got myself a new calculator, and for some reason I got the nicest one available the TI-nspire CX CAS and I am utterly lost. Please excuse my ignorance, I'm about to ask some extremely stupid questions:įirst of all, how you divide? When I try, it gives me the answer as a reduced, improper fraction. How can I convert that to a decimal? Or is there a setting I can change to do it automatically. Similarly, how do I add/subtract/multiply/divide fractions on it? To make the line between the numerator and the denominator is it just the ÷ key?Īlso, I see that there is an "=" button that doesn't actually solve math problems, like the Enter button does. Algorithm First we modify the data to have a lower bound of 0. ![]() This leads me to believe I can enter entire equations and have the calculator solve for x. Is this true? And if so, how do I accomplish that?įinally, will it/how do I get it to do fractional proportions? For example, what buttons would I press to solve this: To do this we subtract the minimum value from each value: Then we modify the data to have an upper bound of 1. I apologize for the many stupid questions, thanks in advanced for the help! (ignore the asterisks.I can't make them go away.) The TI-nSPIRE gives answers as exact (that's why you get the fractions) for an approximate (decimal) answer, press control-enter instead of enter. (You can also change the default in settings/settings/general/Calculation_Mode for exact or approximate answers.)Īn important feature is that different 'documents' can have different settings, so if for example, you create one document for physics class, all of the general settings can be what you need for physics and the calculator will remember them. Then, you can create another document for algebra class and save all of the settings that are correct there. No more wrong answers because you forgot to change to/from radian-degree angles, etc.Įntering fractions uses a "template", all of the templates are available as a menu when you press the template button (just to the right of the 9). The shortcut for the fraction template is to press ctrl-(divide). (There is also a := key that assigns a value to a variable.) The equal sign key can be used to enter equations or to compare the equality of two quantities and return a true/false result. I've had my nSPIRE for a year, and once I learned the different keypresses and shortcuts, I found it much faster & easier to use than my previous TI-8X calculators. ![]() (I upgraded to the nSPIRE CX over the Summer for the improved screen). You can also type the name of any function using the a-z keys instead of clicking through a bunch of menus. This was a big time saver when solving systems of equations using the rref() function.
