TI-89 / TI-89 Titanium
Students explore relative maximums and minimums by drawing tangent lines to a curve and making observations about the slope of the tangent line.
Students use a program to plot a tangent line to a curve. Students will examine the slope of the tangent line to find relative maximums and minimums.
In studying each critical number, students will be able to determine whether there is a relative maximum, relative minimum, or a plateau at that point.
