## Can TI 89 do partial derivatives?

Fortunately, the method described above can easily be automated, because when you ask the TI-89 to take a derivative of a function with respect to a variable, it actually takes a partial derivative of multivariable expressions. Here are the derivatives that were shown above, taken on the TI-89.

What does the second derivative tell you?

The derivative tells us if the original function is increasing or decreasing. The second derivative gives us a mathematical way to tell how the graph of a function is curved. The second derivative tells us if the original function is concave up or down.

### What kind of derivative does the TI-89 take?

Fortunately, the method described above can easily be automated, because when you ask the TI-89 to take a derivative of a function with respect to a variable, it actually takes a partial derivative of multivariable expressions.

### Do you need user defined function for implicit differentiation?

If you have a TI-89 Titanium, or if you have downloaded and installed an updated operating system for an older TI-89 (and if you haven’t – why not?) then you do NOT need a user-defined function for implicit derivatives. You can use the built-in function: impDif(equation, independent variable, dependent variable)

How to find derivative of X with respect to T?

For example, if y = x 3 – 2x + 4, the derivative of y with respect to x can be found as in the screen shot at right. The solution to the problem “If x = 4t 2 +1/t, find the derivative of x with respect to t” is shown at right.

#### When do you need to know the derivative of a function?

The solution to the problem “If x = 4t 2 +1/t, find the derivative of x with respect to t” is shown at right. Sometimes you just need to know the value of the derivative of a function (the slope of the function’s graph) at a particular point.
