To solve exact/approx homework problems on your TI-89 calculator, you will need to use the built-in functions and commands specific to the calculator. These include the "solve" function, the "exact" and "approx" commands, and the "solve(" and "solve(ESolver)" commands.
The "exact" solution on the TI-89 calculator will give you a solution in exact terms, meaning it will include variables and fractions. The "approx" solution will give you an approximate numerical value of the solution.
Yes, the TI-89 calculator has a built-in function specifically for solving systems of equations. You can use the "solve(" function and input the equations and variables to find a solution.
Yes, the TI-89 calculator has a built-in function called "verify(" which allows you to check your answer by inputting the equation and the solution. It will then tell you if the solution is correct or not.
Yes, the TI-89 calculator has a built-in calculus menu which includes functions for solving derivatives, integrals, and differential equations. It can also graph functions and find the zeros, maximums, and minimums of a function.
