18 1. INTRODUCTION TO Mathcad is displayed. That might be due to our variable only has one value, so only a dot is plotted. To see if this is the case, double click the graph box, a popup window will show, by specifying the thickness of the trace we will see the dot if it is graphed. Another reason we don’t see a curve is that the range for y is not properly specified. We can change the lower and upper limit for y variable by clicking the lower and upper left corners, place holders(or number) will appear, change it to the desired value, the graph will appear. So to graph a function, we do: (1) Define the function. (2) Define range value for the variable of your function. (3) Press @ and enter the function name and variable name in proper place holder. (4) Adjust the thickness of the trace.

Unformatted text preview: (5) Adjust the y ranges by changing the numbers on the far left (see the graph below). We have two screen shots here, the first one shows a blanket graph-ing box with place holder and another graphing box display graph of f ( x ) = 1 3 x (3-x ) over interval[-4, 4]. Figure 18. Graph of one function and blank graphing box The second one shows how to graph more than one functions in the same graph box; it also shows the configuration box and change of the weight of the curve. To graph two or more functions in one graphing box, you just type comma(,) after each function name as f(x),g(x), h(t) . If two or more variable name (as in the case of screen cut) you need specify them in the place holder for variable comma separated as x,t ....
