Turning an equation into a graph
For a school assignment I have to turn a number of equations into a graph.
for example y=-56 over 2197 (X+38.5)to the third -7 when X = -45. HELP!!! |
Turning an equation into a graph
Steffi -
Here's the easy way. In column A (starting in A2) type a series of typical X values from within the range of interest. In B2 type the formula, referring to A2 as the variable X, and fill this down alongside all of your X values. I can't parse your formula, but here's an example. Suppose you want Y = 12 + 13 X - 0.003* X^2 In B2 enter this formula: =12+13*A2-0.003*A2^2 You can fill this down by selecting B2, and double clicking on the small black square at the bottom right of the highlighting rectangle. Now make your chart from the data in columns A and B. Make an XY chart, not a line chart. - Jon ------- Jon Peltier, Microsoft Excel MVP Peltier Technical Services Tutorials and Custom Solutions http://PeltierTech.com/ _______ Steffi wrote: For a school assignment I have to turn a number of equations into a graph. for example y=-56 over 2197 (X+38.5)to the third -7 when X = -45.

In addition to Jon's do-it-yourself approach, also look at PLOT manager http://www.tushar-mehta.com/excel/so...ger/index.html Does something similar but concentrates its efforts where the function is more curvy. -- Regards, Tushar Mehta www.tushar-mehta.com Excel, PowerPoint, and VBA add-ins, tutorials Custom MS Office productivity solutions |
