Make sure you give it the appropriate number of arguments. The limit() function takes three or four arguments.

- The expression. For example, sin(x)/x
- The variable. For example, x
- The point at which the limit is to be taken. For example, 0
- (optional) The direction from which the limit is to be approached, negative for from the left, positive for from the right, 0 for both. Defaults to zero if not given.

You are trying to use a command or a function that requires you to give it some information to use. The information required is supplied between parentheses. What is inside the parentheses is called the argument(s). Each argument must have a certain type of data : scalar, vector, list, matrix. It happens that one of the arguments in your command or function must be of type list. Before calling the function you must have defined (created) that particular list and populated it with necessary values.

That is all I can say, because I have no idea what you are trying to do.

**Dimension
mismatch** error occurs when arguments are not with same dimensions. Two or more arguments must be of the same
dimension. For example, [1,2]+[1,2,3] is a dimension mismatch because the matrices
contain a different number of elements. By the way, it it very easy to resolving
your problem with differentiation. See captured image

As a result of differentiation you had to obtained:

(3b+2c)cos2x+(3c-2b)(sin2x)e^(3x)+2ae^(2x)

The ExpReg command is in the MATH/Statistics/Regression menu. The first two arguments are lists containing the x and y values. An optional third argument is a frequency list. Two additional optional arguments are lists of category codes and a category include list.

Full details are in the manual under ExpReg, page 819 in the version available at

Put both arguments inside the parenthesis.

2ND MATH 7 3 6 , 3 ) ENTER

The comma between the 6 and 3 is required (it's the key just above the 9).

Hello,

Here is a screen capture of the integral.

The dummy variable x may contain some previously defined value. Clear old values . In Home folder [2nd][F6: Clean Up][ 1:Clear a-z] [ENTER][ENTER] or [2:NewProb][ENTER][ENTER]

Make sure you insert the multiplication sign. And do not forget to put the argument x of the function inside parentheses.

Hope it helps.

the problem is you haven't given it anything to solve...

always add a comma and the variable after any solve, differentiate or intergrate problem...

eg:

solve(x^2=4) is wrong!

intead put:

solve(x^2=4, x)

Hope this helps

I reset my calculator and this solved the problem. To reset your calculator press [2nd], then [6] (Mem), press F1 (reset), Select 3 for all memory, and select Yes.

I reset the calculator and it did its job- though a solution would be handy.
