- Introduction
- ------------
- 'Trigno Graph' was originally developed as a study aid to help mathematics
- students quickly sketch graphs of complex trignometrical equations. However,
- in it's current state, 'Trigno Graph' can now be used to plot almost ANY
- graph which can be represented by a mathematical equation. (straight lines,
- curves, anything...) I have also added support for graphically representing
- series'...
-
- The equations and axis of the graph can quickly and easily be modified, and
- the graph redrawn - effectively enabling you to ZOOM in or out of the graph.
-
-
- Starting Up - DOS
- -----------------
- i. Log onto the directory in which Trigno Graph is stored
- ii. Type "MOUSE.EXE" <enter>
- iii. Type "GRAPH" <enter>
-
- Starting Up - Windows '95
- -------------------------
- i. Either (a) Goto DOS-PROMPT
- Or (b) Goto SHUT DOWN -> 'RESTART IN DOS MODE'
- ii. Follow instructions as for DOS (above)
-
-
- Using 'Trigno Graph'
- --------------------
- Before you can plot an equation, you must first enter in the limits
- for each of the axis.
-
- To set/alter graph axis: Click on relevent box
- Enter value
- Press 'Enter'
-
- To create a graph: Click on equation box I or II
- Enter equation
- Click on 'draw'
-

- Notes
- -----
- i. Entering equations exactly as you would see them written on paper.
- ii. Use brackets around power terms (except for power-2).
- iii. Square and round brackets are identical.
-
-
- Plotting Series'
- ----------------
- To plot series in the form Xn+1 = f(Xn):
- (a) Click on 'Function' until it changes to 'Series'
- (b) Type out the equation exactly as you would a normal equation,
- but where X stands for Xn.
