This should be the CALC menu. Press either F2 or F3. These should correspond to nDer and der1. Both of these functions preform the same task.

Something does not work as expected? At this point on the curve, it slopes upwards, hence a positive derivative. Another way of looking at a derivative is the slope of a tangent line at a specific point.

A tangent line is a line which touches a function without crossing it at a specific point. Finding a tangent line to a curve is one of the most elementary uses of the derivative. This image shows the derivative at various points as the slope of a tangent line. When the derivative is positive, the line is green.

When the derivative is negative, the line is red. When it is zero, the line is black. Unfortunately, this function only returns the derivative of a single point. While there is no built-in function on the TI Plus and TI Plus to take a derivative in general, you can read more about using an application to enable this functionality here. Next, enter the function you want to differentiate, press , , enter the function variable, and add a closing parenthesis to finish the expression.
