Question about Texas Instruments TI-89 Calculator

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.

**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)

You already have something stored with the name x. Either get rid of it or use a different name for the variable of integration.

You can see what variables you have stored by pressing 2ND [VAR-LINK] (the minus key).

Hello,

The default variable for the integral is x. If you have a product between two litteral symbols the * must be inserted. Arguments of functions must be enclosed between parentheses. To avoid errors clear the variables before the integration: [2nd][F6:Clean Up] [2:NewProb][ENTER]ENTER]

Hope it 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.

An argument must be in a specified domain. For example, ans(100) is not valid because the argument for ans() must be in the range 1–99.
