This means that the function will be graphed in boldface. Set Ymin and Ymax similarly for the range. It is a named memory space. This returns your calculator to a sort of pristine virgin state. In polar coordinates mode, this key gives you a q instead of an X.
Hitting that button is a quick easy way to enter an X. At this point, you have several choices. But it can get confusing to see which is which. Finally, use 2nd QUIT to return to the main screen.
Finally, be careful as always about order of operations! That actually puts the calculator in Degree mode.
For instance, if I run a QuadReg on the data above, the calculator gives me: Now, use the right arrow to choose Par. Menus, and Stupid Trig Tricks A lot of option-setting is done through menus, and the way they work can be confusing at first.
This brings up a menu where you can zoom in, or zoom out, or other things. The result looks a bit like a valentine. This is useful in a lot of situations, but particularly when you want to do something iteratively. This brings up a menu. Memory clearing the cure-all Sometimes, your calculator gets into a funny mode.
The calculator is now in polar coordinates mode. You are now asked if you want to reset "all memory" or just "defaults. The calculator does not graph your curve for you, but it does tell you what the curve is.
The resulting display is shown below. Arrow down to where it says Func short for "function" which is a bit misleading since they are all functions. Curve fitting, or regression "Regression" is a peculiar word that means you have a bunch of points, and you want to find a particular curve that most closely fits them.
Hit the down arrow to go to Y1T and in that space type the same formula, but with a sin instead of a cos.
As a final experiment: I always ignore them. Tell it that yes, you really do. This screen shows the points 2,14,3and 5,8.The College at Brockport: State University of New York Digital Commons @Brockport Lesson Plans CMST Institute Absolute Values and Inequalities using TI.
Table values By default, when you create a table of values, the table starts at X=0 and then moves on to X=1, X=2, and so on. You can see this behavior in the sample table shown above. But just as you can change the window of a graph, you can change the values used in a table. Hit TBLSET (in yellow above the WINDOW key).
