1 Introduction to FX Graph 5

2 Getting Started Click on the y= button (or right click on the graph) to enter a function

3 Each Line is a Function The function entry section of the Quick Entry screen allows for multiple lines. Each line will be graphed as a separate function.

4 Points Of Interest FX Graph finds points of interest automatically. As you move the mouse around, FX Graph will show you any points of interest near the cursor.

5 Right Click Menus 1 Many features are accessed by right-clicking on the graphs A.Right-clicking at point A will open the Quick Entry screen - the one we have been using to enter our functions. B.Right-clicking at point B will open the Scales screen which will allow you to set the scales you use for the function. C.Right-clicking at point C will offer a right click menu (providing FX Graph has found the function and displayed it for you).

10 Cartesian / Inverse Cartesian Functions FX Graph never needs to be "told" what type of graph to draw - it automatically determines the graph type by what you type. To draw a Cartesian function, just use x's – to draw Inverse Cartesian functions, use y’s. 3x2 + 2x - 4 y = 3x2 + 2x - 4 f(x) = 3x2 + 2x - 4 3x2 + 2x y = 0 3y - 4/y x = 2y2 + 3y - 4 f(y) = 3y + 4

11 Using the Function Entry System 1 The function has no y = but FX Graph will interpret it as a Cartesian function anyway. We have not had to do anything to get FX Graph to interpret x2 as x squared. Most of the time, FX Graph will find powers automatically. We have used the / sign to represent division. We have wrapped the numerator and denominator of the fraction in brackets - not too tricky as most mathematicians realize that the fraction line is a de-facto bracket. We have used sqrt to represent square roots. We could have used sr instead.

23 Complex Numbers & Argand Diagrams 3 …solve complex powers…

24 Complex Numbers & Argand Diagrams 4 and graph some graphs of the magnitude of z

25 Parametric Functions Note use of semicolon

26 Implicitly Defined Functions

27 Slope Fields

28 Differential Equations

29 Tangent / Secant Lines You can add tangent and secant lines to Cartesian functions

30 Integrals You can add integrals to Cartesian functions

31 Tables of Values Tables of Values can be added to most functions

32 Setting Domains 1

33 Setting Domains 2

34 Setting Domains 3 The second style is slower, but more versatile.

35 Plot As Points

36 Constants 1 FX Graph 4 interprets a, b, c, d and m as constants in your functions

37 Constants 2 Constants can be used just about everywhere!

38 Families of Curves x2 +a/x
