Setting the mode on your calculator is one of the easiest things to do, yet is still very important. Say you want to know what the sine of 90° is. Type in sin(90) and you should get 0 right? Not if you're in radian mode, it will give you .893997. That's why i'm here to tell you how to change your settings and what they all mean.
It may not look like it at first, but every line in the mode menu is for a separate setting. The first of each line is the default (what the calculator starts at and resets to) while highlighted options are those that are set. To change the settings, simply move the flashing box using the arrow keys and hit [ENTER] when you're over the desired setting.
The settings are, from top to bottom: Number style, Decimal place, Angle type, Graph style, Graph line style, Graph line order, Imanenary number settings, Screen style
This sets how numbers are displayed. Options:
Normal - dispays all the digits of a number just like everyday stuff
Scientific - Displays numbers in Scientific notation (ie. 100 would be displayed as 1E2, which means 1 * 10^2)
Engineering - simialiar to scientific notation except that there may be multipal digits before the decimal place
Determines how many digits will appear after a decimal point. Float will display as many as needed up to 9.
Sets your angles to either Degrees or Radians. See our Angle page for more on degrees and radians.
Sets the type of Graph used.
Function - a normal xy plane (cartesion graph)
Parametric - gives a value based off of 2 others, sort of a cheap 2D version of a 3D graph
Polar - these are fun, but they'll confuse the heck out of you. Instead of x and y, you have the radius and angle.
Segquence - good for ploting points, like lists, though I perfer using Stat Plot
This lets you toggle from connected points on your graph to just dots. Solid lines are nice but sometimes are missleading.
Sequential will draw the first function you have completely before starting the next. Simultaneous will draw all of the functions at once left to right. Of course this is much slower per function but both end up taking the same amount of time.
Real is your normal everyday stuff. a+bi and re^Ø will display answers as complex numbers and polar complex numbers respectively.
Allows to have a Full screen or split it either Horizontally or vertically for graph/table format (G-T).
