What is inverse of log?
Some functions in math have a known inverse function. The log function is one of these functions. We know that the inverse of a log function is an exponential. So, we know that the inverse of f(x) = log subb(x) is f^-1(y) = b^y.
How do you use the rref in TI-89?
Reduced row-echelon form (rref) can be obtained on the TI-89 in one step by using rref(matrix). To enter rref(, press CATALOG button (Row 3 Column 3), followed by s (key 3) and then use the up arrow to select rref(. Press ENTER button to place rref( on the command line.

How do you use quadratic formula ON TI 89?
solve(equation, variable) Examples: 1. To solve the equation 2×2 +3x−4 = 0, use: solve(2x∧2 + 3x – 4 = 0, x) enter [Note that the comma is a necessary part of the command and is available on the TI-89 keypad. Also enter the right parenthesis. Two roots will be displayed, equivalent to the solutions found “by hand” using the Quadratic Formula.] 2. solve(2x∧2 + 3x + 4 = 0, x) enter
How to graph polar equations on TI 89?
“POL” is selected to enable polar graphing. Next, we can go to the equation entry screen by pressing the Y= button, just like for graphing equations in rectangular coordinates. This time, instead of seeing “y=” for each equation, it prompts for each equation in terms of r.
