SUMMARY
The TI-89 calculator is designed to provide both exact and approximate results for derivatives. Users can switch between modes, but if a decimal is returned instead of an exact expression, it may be due to a variable value being stored. In this case, pressing the diamond button before ENTER in exact mode can yield a fraction. Clearing stored variables can resolve issues with unexpected outputs.
