**PowerPoint**Add formulae**Course contents**• Overview: Typing math formulae • Lesson1: Type a simple formula • Lesson2: Type a complex formula Add formulae**Overview: Typing math formulae**• When you prepare slides for an engineering course, you need to display mathematic formulae. • This course will tell you how to type such formulae in PowerPoint. Add formulae**Course goal**• Put a formula in you presentation. • Navigate and edit a formula. • Create a simple formula on a single line or a complex multi-lines formula. Add formulae**Lesson 1**Simple formulae**Insert a formula**Use the Insert menu to add a formula to your PowerPoint presentation. • Click on the Insert menu and select Object. • Select Microsoft Equation and click OK. Inserting a formula via the Insert menu. Add formulae**Enter the Equation Editor**• The window that opens has some symbols at the top and a large equation space at the bottom. • You type the equation by selecting symbols from the menus at the top and typing other characters on the keyboard. • The equation goes into the dash box. The Equation Editor. Add formulae**Your first equation**• On the keyboard you type the characters: m, =, 3, x, - and 7. • Notice how the equation editor adds some space around the equal sign and minus sign. • The Equation Editor tries to follow the typographic rules for presenting mathematics. A simple equation. Add formulae**You are done**• When you are done with typing your equation, you exit the Equation Editor and return to the PowerPoint presentation. • Click on the File menu. • Select Exit and Return to Presentation. Exit the equation editor. Add formulae**PowerPoint and the Equations**• It does not look too good. • Equations do not integrate well with PowerPoint: they are not part of the text, they are a separate object. • Size is too big, color is wrong. • You need to fix this. Add formulae**You need to change the color.**• The equation appears with a default color black, this is probably not the color used for your presentation. • With the mouse, Right Click on the equation. • Select Show Picture Toolbar. Edit the equation color. Add formulae**Use the Recolor Picture tool.**The Recolor Picture tool is started when you click on the icon • On the Show Picture Toolbar, use the Recolor Picture tool. Use Recolor Picture. Add formulae**Use the Recolor Picture tool.**• In the Recolor Picture tool select the new color you want to apply: for example change black into white. • Click OK when you are done. Use Recolor Picture. Add formulae**Resize and move the equation**• The equation is of the right color. • Use the round handles to move and resize the equation like any object in PowerPoint. Add formulae**Resize and move the equation**• Adjust the size of the equation to be close to the size of the text. • If the equations stands alone on a line, it should be centered. You can also use the arrows to adjust the position of the equation. Add formulae**Add symbols to the equation.**To add a σ click on the menu that represents Greek letters and select the character σ. • The top line in the menu of the Equation Editors give access to some symbols like Greek letters and others. Use Greek letters and other symbols. Add formulae**Modify a symbol.**The menu is special: it does not add a symbol, but it modifies the symbol just before the cursor. • Select the modifier from the menu . • Position the cursor (blinking bar) just after the symbol you want to modify. Add a modifier to a symbol. Add formulae**Type a function.**• Mathematic symbols are type in italics like x. • Name of a function are typed in Roman like Cos(x) or Factoriel(2). • The Equation Editor knows how to type Cos, but you need to modify Factoriel by yourself. Function names are in Roman. Add formulae**Type a function.**• To type Factoriel in Roman: • Highlight the word Factoriel. • Click on the Style menu. • Select the option Text. Function names are in Roman. Add formulae**Suggestion for practice**• Prepare one page presentation and type the • following equations: Add formulae**Lesson 2**Complex formulae**Complex formulae**Not all formula can fit on a single line. Mathematics need superscripts, subscripts, array of values for a matrix, etc. The second line of menu give access to complex symbols. Their size varies with the equation. A complex formula. Add formulae**Build step by step**You know how to type Select the quotient from the menu You have an horizontal bar with two placeholders. A complex formula. Add formulae**Build step by step**Select symbol Σ from the menu The cursor is in the top placeholder. There are 3 placeholders with the symbol Σ. A complex formula. Note that the fraction bar has extended. Add formulae**Build step by step**Select the subscript from the menu Type m. A complex formula. Add formulae**Build step by step**Fill in the remaining placeholders. Your equation is completed. Your can use the key Tab to skip from one placeholder to the next one. Placeholders are in natural order, the reading order of the equation: sum of the m i for i equal one to n divided by n. A complex formula. Add formulae**What sum symbol to choose**• With the placeholders for the boundaries above and below the Σ symbol; • With the placeholder for the boundaries on the right of the Σ symbol. • There are different type of sum symbols: Add formulae**What sum symbol to choose**You use the type above/below for display presentation: The equation is isolated on the center of a line. Add formulae**What sum symbol to choose**You use the type on the right Note the fraction bar that you get from the menu for in-line presentation: the equation is part of the line of text. The equation is not as high as the display presentation; it integrates with the text. Add formulae**Vectors and matrix**Drawing matrix is easy with the Equation Editor. You need big delimiters, like parenthesis, brackets, etc. And inside the delimiters, a table of elements. A 2 by 2 matrix. Add formulae**Build step by step**The menu gives you a choice of delimiters. These delimiters will adapt their size according to the contents. • Click on the menu . • Select the parenthesis ( ). A 2 by 2 matrix. Add formulae**Build step by step**The menu gives you a choice of tables of one or two dimensions. • Click on the menu . • Select two by two table. • Fill in the placeholders, you can use the Tab key to jump from one placeholder to the next one. A 2 by 2 matrix. Add formulae**Managing space**Lets consider the equation The Equation Editor does not always do a good job at managing the space between symbols. Spacing is incorrect at all the places with a red mark. Correcting the spacing. Add formulae**Build step by step**The menu gives you access to a choice of spaces that you can use in your equations. • Select the space you want to add from the menu • Move the cursor where you want to add some space. Correcting the spacing. The marks for extra spacing will not show on the final equation. Add formulae**Suggestion for practice**where ω represents… The speed v can be represented as for all H and h. • Prepare one page presentation and type the • following equations: Add formulae
