Finding The Derivative Of A Function At A Point (The Slope) - Texas Instruments TI-NSPIRE Software Manual

Notice that the integral between the bounds and with respect to the
x-axis is shaded on the page.
Tips:
• To stop the boundary line at a tic mark on the x-axis, select the
tic mark.
• For precise integral boundaries, type a numerical value instead
of graphically placing either or both lower and upper boundary
lines.

Finding the derivative of a function at a point (the slope)

1. Graph a function.
2. Select a point on the graph.
3. From the Points & Lines menu, select the Tangent tool (
4. Construct the tangent at this point.
