Using 'nDeriv' on a TI Plus. Thread starter Naur Start date Oct 6, Tags nderiv ti JavaScript is disabled. For a better experience, please enable JavaScript in your browser before proceeding. Jun 88 5. On my TI Plus graphics calc, I've found there's a function called nDeriv, that can be used to find a derivative. It sounds useful, so how do I use it? May 2, 2, Chicago, IL. Naur said:. Reactions: Naur. I'm not sure where my manual is.

For example,. 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.
