Graphmatica an overview

  1. 1. GRAPHMATICAA Quick StartByMuhammad MuddassirKhan
  2. 2. Muhammad Muddassir KhanMBA (MIS) – Institute Of Business ManagementMCS (SE) – SZABISTM.Phil (In progress with Karachi University)PMP – Shall certified by end of this yearPrimavera Trainer12 year as “Free lance IT Trainer” / The FacilitatorAisha Bawany Academy as “HOD – Computers & Mathematics”Trainer Profile
  3. 3. Graphmatica draws mathematical graphs like,y = x2 - 6x + 5A powerful, easy-to-use, equation plotter with numerical and calculus features:Graph Cartesian functions, relations, and inequalities, plus polar, parametric, and ordinarydifferential equations.Up to 25 graphs on screen at once.New data plotting and curve-fitting features.Numerically solve and graphically display tangent lines and integrals.Find critical points, solutions to equations, and intersections between Cartesian functions.Print your graphs or copy to clipboard in black-and-white or color.About Graphmatica
  4. 4. When you start Graphmatica the first time, you might notlike the layout - funny colors, small numbersStarting
  5. 5. Change the numbers (scale) with View/Grid RangeChange Scale
  6. 6. Choose better colors with Options/Graph Paper/Colors (choose White):Better Colors
  7. 7. Now you will have white paper with colored lines, and you candraw your first graph.In the formula-box, type : y = x^2 + 2x - 4(The ^ symbol stands for power, so x^2 means x2 .Draw First Graph
  8. 8. To add another graph, type the formula in the formula boxand press [Enter].Draw Another Graph
  9. 9. Find the coordinates of the point of intersection by movingthe cursor to that point (trace the graph), and then read thecoordinates at the bottom of the screen.Tracing Coordinates
  10. 10. There are two ways to zoom in and out :- View/Grid Range - change the grid-range by typing limits for x and y- Mark and Zoom - hi-light an area then click the zoom button. Usethe Default Grid button to return to the normal view.Zoom
  11. 11. Use Tools/Find Intersection to automatically find the points of intersection.This gives better results than tracing, as tracing only finds approximatecoordinates - e.g. 1.995 instead of 2.0 .Automatically Find Intersection
  12. 12. You can mark points on the graph - for example, the points ofintersection, by using View/Data Plot Editor. Type the coordinates ofthe points you want to mark with dots.Marking PointsThis will squash your graph tomake room for the data table.After typing the points, youcan hide the data-table againbut the dots will stay.
  13. 13. You can label points or add other annotations (notes) to your graph.Use Edit/Annotations. If you want to move the annotation later, double-click on it, click the [Place] button, then click on the graph to place thatannotation.Adding Labels (annotations)
  14. 14. Use Edit/Copy (BMP) to copy your graph. Then you can paste it into adocument. Copy using EMF might work better for some word-processors, but BMP probably works for most normal applications.Copying the Picture
  15. 15. Before copying, you might want to resize the Graphmatica window, asresizing in a word-processor might make the picture ugly.
  16. 16. Use File/Save or Save as to save your graphs. You might alsowant to use File/Save Setup Info to save your color and sizesettings, so these will stay the same for new graphs.Be aware that this doesnt actually save your picture, butrather saves all the formulae you wrote. If you drew lots ofgraphs and erased them, they will all appear again whenyou open the file next time.Saving your Work
  17. 17. There are two ways to erase a graph. Right-click on the graph then choose:- hide - makes the graph disappear, but keeps the formula- delete - makes the graph disappear and throws away the formula.Erasing
  18. 18. You must use Graphmatica notation to define functions. Hereis a summary of common symbols. More details availablein Graphmatica Help / Graphing Equations / Operator Table.Summary of Symbols
  19. 19. Graphmatica contains someadvanced features forinvestigating graphs.Advanced Functions (Calculus)
  20. 20. Click on the curve you want to investigate. Then use Calculus /FindCritical Points to find the zeroes (roots) of the function. For theparabola, this also finds the vertex.Roots (Zeroes)
  21. 21. Use Calculus/Draw Tangent Line to find the slope of a curve at a point.Click on Draw Tangent Line, then click on a point on the curve.Slope (Tangent Line)
  22. 22. Use Calculus / Derivative to find the derivative of a function - this willalso draw a graph of the derivative. If you dont want to see the graph,hide it. Click on the graph of the derivative to see its formula (at thebottom).Derivative
  23. 23. Use Calculus / Integral to calculate an integral - this calculates the valueof the area as a number - it will not give a formula as an answer. Youcan find the area between to functions, or just the area under a function(change the second equation to <none> ).Integral (Area)
