That is a piece of cake. just go to the two Lists that you are using for the equation and see if they are the same length.

I get a ERR: DIM MISMATCH when I try to use graph an inequality using the inequalz app


Your TI-84 Plus displays the ERR:DIM MISMATCH error if you are trying to perform an operation that references one or more lists or matrices whose dimensions do not match.
For example, multiplying L1*L2, where L1={1,2,3,4,5} and L2={1,2} produces an ERR:DIM MISMATCH error because the number of elements in L1 and L2 do not match

How do I get rid of the ERR:DIM MISMATCH message?


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.

When trying to write simple graph lie Y=x+3 i get err: DIM MISMATCH QUIT


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 graphing linear function.

My calculator displays an error message, "ERr: Invalid DIM" when I try to run a LinRegTTest. X and Y are using the right lines of data, L1 and L2.


If the message you got is ERR:DIM MISMATCH 1:Quit, the two lists you are using do not have the same dimensions. One list is longer than the other.
