I had this problem too, turns out that if any of your y-coordinates are 0 or negative you will get a domain error. Hope this helps.

I am trying to enter a exp to an complex number and am getting a domain error. How do I clear it up


You got a domain error because your angle unit is not set to radians.
Change the angle unit in the MODE configuration screen. In the following screen I calculated the same expression under EXACT and APPROXIMATE calculation formats.

Domain error occurs if you using polar form of complex numbers in Degree or Gradian angle units.
You have to set up Radian mode and then input complex value. See captured images

At first, you can enter a complex number in r*exp(i*theta ) form. This is exponential form of complex number. However, use this form in Radian angle mode only. It causes a Domain error in Degree or Gradian angle mode. To resolving this problem type Mode then F1 and set up Radian mode

I keep getting the following when opening or sending mail: The message could not be sent. The setting for your outgoing email [SMTP] server might need to be configured. To find the server settings for...


Quick summary:
It appears that email address does not exist - which is why your email program was unable to send the message. There may be a small typographical error in the address - which you would need to correct in order to send the message successfully.

Background:
The error message you received says the "domain does not resolve". That means your outgoing server (which is used for sending messages) couldn't find the information about the recipient's address -- and more specifically, the "domain" of the recipient's address. (That's the portion of an email address following the "@" sign.)

The error message indicates the domain of the recipient's address is "quickfireprocuctions.com". But a quick check of domain registration records indicates there is no registered domain by that name. And if a domain is not registered, there can't be any websites or email addresses which use that domain name.

However, there is a properly registered domain "quickfireproductions.com" (with a "d" rather than a "c"). That seems much more likely - as the combination of recognizable words ("quick" "fire" "productions"). That domain is registered to owners in Florida, USA. See details at: http://whois.domaintools.com/quickfireproductions.com

Solution:
If that registered domain name sounds right, then you should revise the email address in your message to use the correct domain name (i.e., replacing the "c" with a "d").

How to find the best fit for exponential decay?


The error comes from the vanishing values at the tail of the function. The exponential function does not vanish except for -infinity. Truncate the lists by removing the pairs (5,00 and (6,0) or fudge up the data (5, 1E-5) (6,1E-6) and you will get your equation of best fit.

I am including a link to a post of mine where I show how to perform an exponential regression. JUST IN CASE you need additional information on the subject.

I would like to input a graphing range with a restriced domain. For example SIN X with a RANGE -2pi to 2pi you see that, 4 half curves. Now I would like to see the same SIN X plotted in a Minus ONE to ONE...


I am enclosing a link to a web page that gives you the definition of the domain of a function and its range. You should read it to correct the confusion you entertain between domain and range.
In what follows I will speak of X and Y values.
Let me restate what I think you wanted to do. Ignore my rambling if you do not recognize your intention.

You want to draw the sin(X) function for X varying from Xmin= -2*pi radians to Xmax=2*pi radians. However, it you do not specify the Ymin and Ymax values for the vertical window dimensions a big portion of the screen is not used (vertically) and you want the height of the curve to take most of the screen. Specifically you want to set the vertical height of the window to go from Ymin=-1 to Ymax=1.

Press [SHIFT] [F3:V-Window] to set window dimensions.
On line Xmin= type : (-)2*[SHIFT][EXP] (Pi); or just (-) 6.3
Press [EXE] to validate the choice
On line Xmax= type 2*[SHIFT][EXP] (Pi) or just 6.3
Use down arrow to highlight the line Ymin= and enter (-)1
On line Ymax= type 1

You may or may not want to change the X(scale) and the Y(scale)
Press [EXIT] to exit the window settings.
Draw your graph.It will occupy all the screen.

Here is what you will get.
