150 Using Graphs & Geometry
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.
Tangent line created for
the function. The point of
tangency is labeled.
