Introduction to FX Draw 4 Flyout Toolbars Any tool with a red triangle hides a “flyout” toolbar containing extra tools. Click and hold the left mouse button for > 1 second. GAD - Geometrically Aware Drawing FX Draw provides dynamic feedback that shows the geometric relationships in your drawing. Make sure that GAD is turned on! GAD Has A Memory! Any relationships that you have created with GAD are remembered. Move the base object and all relationships are maintained. 47° 47° Right Click Most figures have extra properties that can be accessed by right-clicking on the figure. Figure Information If you select a figure (anything you have drawn) and then hover the mouse near that figure, FX Draw will display some information about that figure. Annotations When FX Draw is displaying figure information, right click your mouse. You are given the opportunity to add an annotation. Annotations are dynamically updated as the figure changes. Three Point Circles Many tools require that the object be defined by three points – triangles, three point arcs, three point ellipses, three point circles. A good way to practice using these tools is to draw a circumcircle using the three point circle tool. Using the Compass FX Draw 4 adds a Compass tool that works just like the normal, centre point / point on radius tool, but then remembers the radius so the second and subsequent circles have the same radius. Use the Compass tool to draw this “daisy”. Marking Angles FX Draw 4 can mark angles with one-click. If you right- click on a marked angle, you can select from 10 different angle marking options. Angle marks are dynamic. Move the lines and the angles are re-measured. 42° Rulers & Protractors The ruler and protractor tools let you demonstrate measurements on paper and on screen. 80 100 1 70 10 60 0 90 12 0 13 10 80 7 50 110 0 0 20 60 0 1 50 14 3 40 1 0 0 14 15 40 30 0 0 15 30 160 20 160 20 170 180 170 10 10 0 180 10 0 0 20 30 40 50 The Mathematics Tools Function Graphs Statistical Graphs Normal Distribution Curves Venn Diagrams Number Lines Grids and Dots Unit Circle Tree Diagrams Clocks Function Graphs The function graphs tool lets you draw just about any graph that can be defined by a function Cartesian Functions Conic Sections Inverse Functions Shaded Integrals Polar Functions Points and Vectors Parametric Functions Tangent Lines Implicitly Defined Functions Constants and Animations Systems of Inequations Complex Numbers Quick Entry Screen Cartesian Functions Enter functions in terms of x (y = is optional). FX Draw can quickly find and annotate points of interest on the graph. y Poin t of In tersectio n y 10 ( 2.9 25852 , 6.925852 ) 2 1.5 1 0.5 5 3 x – 2x – 1 2 2 4 5 2 x -0.5 3 3 3 3 -1 -1.5 - 10 -5 5 10 x -2 -5 Local Min imum ( 1.3 333 , -2.1 852 ) Axes in terms - 10 of π Inverse Functions Enter functions in terms of y (x = is optional). y 10 y + 3y – 4 2 y 5 - 10 -5 5 10 x -5 - 10 Polar Functions Enter in terms of r and th (FX Draw converts th into θ).

You can even put them into the bounds of integrals. Statistical Graphs FX Draw 4 supports a large number of statistical graph types. Box & Whisker Plots Column Graphs Dot Frequency Diagrams Cumulative Frequency Plots Histograms Frequency Polygons Back-to-back Histograms Residuals Graph Scattergraphs Stem & Leaf Graph Line Graphs & MPA Triangular Graph Bar Graphs Statistics Graph Properties Data Generators FX Draw 4 includes handy data generators that can save you hours of time. Just fill in the blanks and push OK. Box Plot Example Part 1 Use the Normal Random Number Generator to generate some data into Column A – and then use the generator again to generate data with a different mean and standard deviation into Column B Box Plot Example Part 2 Choose Quick Graph from the Right Click Menu on Columns A and B. Then press the Graph Type button and choose a box plot Box Plot Example Part 3 0 20 40 60 80 100 Other Statistical Functions FX Draw’s statistics tool can also: Produce summary statistics for one variable and two variable data Perform regression analysis for seven regression models Handle grouped data and frequency tables Produce frequency tables, cumulative frequency tables and grouped data from raw data Transform data using a variety of functions Normal Distribution Curves The normal distribution curve tool gives you quick access to shaded normal distribution curves. You can also add annotations to the curves. 0.4 P(z < -2) = 0.0228 P(-1 < z < 1) = 0.6827 P(z > 1.5) = 0.0668 0.2 -4 -2 2 4 -4 -2 2 4 Venn Diagrams 200 60 20 50 60 10 10 0 40 20 20 10 30 10 20 40 30 50 70 10 140 40 Number Lines Enter functions onto the number lines as x <= 10, x <> 4, x = 5, x > 3.

Unit Circle The Home Key, Page Up, Page Down, Up Arrow and Down Arrow keys can be used to animate a unit circle. Tree Diagrams Enter a tree’s “shape” using the number of branches at each level. For example, this tree is 4,3,2. Gallery Images Gallery images provide hundreds of pre-drawn images that you can use as the basis for your own diagrams. Gallery Tips 1 Gallery images have “direction”. This means that each gallery image can be used in many different ways. Each of these images has come from the same “base” gallery image. Gallery Tips 2 After you have drawn a gallery image, you can “ungroup” it (Ungroup from the Edit menu). This gives you access to the individual components of the image and lets you modify it to suit your needs.
