DIVIDE BY 0 DOMAIN Duplicate Name Error in Xmit ILLEGAL NEST INCREMENT INVALID INVALID DIM ITERATIONS ¦ You are attempting to divide by zero. This error does not occur during graphing. The TI.82 allows for undefined values on a graph. ¦ You are attempting a linear regression with a vertical line. ¦ The argument to a function or instruction is out of the valid range. See Appendix A and the appropriate chapter. This error does not occur during graphing. The TI.82 allows for undefined values on a graph. ¦ You are attempting a logarithmic or power regression with a MX or an exponential regression with a MY. Unable to transmit item because a variable with that name already exists in receiving unit. ¦ Unable to transmit item. Check to see that the cable is firmly connected to both units and that the receiving unit is in Receive mode. ¦ É was used to break during transmission. You are attempting to use an invalid function in an argument to a function; for example, seq( within expression for seq(. ¦ The increment in seq( is 0 or has the wrong sign. This error does not occur during graphing. The TI.82 allows for undefined values on a graph. ¦ The increment for a loop is 0. You are attempting to reference a variable or use a function in a place where it is not valid. For example, Yn cannot reference Y, Xmin, @X or TblMin. ¦ The dimension of the argument is not appropriate for the operation. ¦ Matrix element dimensions and list element dimensions must be integers between 1 and 99. ¦ A matrix must be square to invert it. solve( has exceeded the maximum number of iterations permitted. Examine a graph of the function. If the equation has a solution, change the bounds and/or the initial guess. B-8 Reference Information
