Hi,
I am not sure I understand what you mean. In mathematics, 'e' is a particular number called the base of the natural logarithm. Its approximate value can be displayed by a calculator by taking the exponential of 1. Since its value is 'known', what is there to solve for?

But if you want to calculate exponentials of numbers you press [2nd][LN](e^x) . The screen displays e^( . You enter a number, close the parenthesis and press [ENTER].

Hope it helps.
Thank you for using FixYa and for rating ths solution.

Simple:

Hit this sequence:

"ZOOM" "0"

That is for the "Zoom Fit" option. The calculator does not like the window you have for the equation you've given it. With this option, it will automatically give you the best fit in the window for the equation!

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

### If i want to plot the graph on cy calculater,suddenly undefined error used to apper .how to fixed thin problem

Hello,
Clear all ram
[2nd][MEM][7:Reset][1:All Ram].

To enter a function to graph ex: Y1=sin(x)
Press function key [Y=].
On first line where i says Y1= , enter the function [SIN][X,T,theta,n][)][ENTER]
Then press [GRAPH]
If graph is too flat adjust the window by pressing [WINDOW] and hoose different values for Xmin, Xmax, Ymin,Ymax.

Hope it helps.

### Calculator

Well it seems that you are graphing stat points and forgot to turn them off. This can be easily fixed by going to 2nd and Stat Plot then make sure all the stat plots are turned off. This should solve your issue.

### How to use the texas instruments ti 83 plus

Srry my friend the ti 83 is no magnificent Ti-89. meaning: you have to solve it yourself. There is a method for graphing though. Set the equation equal to zero and then plug the stuff on the other side of the equation into a graph by pressing y= and then typing it in. Then hit graph. Wait for the graph and then hit 2nd calc and select zeros. Bring your cursor using hte arrow keys close to where the line hits the x axis and press enter and then do the same except to the right of that point and then press enter twice and it will display the y which should be the answer
There are quadratic formulas for calculators programmed in tibasic for the calc but other than that there is no way to solve it
