Find where to buy the TI-84 Plus CE graphing calculator in a variety of bold, fun colors. Download free 90-day trial versions of the most popular TI software and handheld emulators. Bring a new dimension of learning to your classroom with activities that put math in motion. Explore teaching strategies to help students succeed on the SAT® and ACT® math tests using TI technology. Drive deeper, more relevant understanding of science in middle grades and high school. Students will calculate the second derivative of functions, inspect a graph and give the intervals for concave up and concave down and find the point of inflection. Students will explore the higher derivatives of several functions and relate these to the shape of the function graph. Students will use a nested derivative command to find the second derivative of each function. Students will graph the function and its second derivative on the same screen to discover how the function's second derivative relates to the function's shape. Students will then find the equation of the tangent line at specific x-values. Students will use this information to find the concavity and point(s) of inflection of the function. © Copyright 1995-2020 Texas Instruments Incorporated. All rights reserved.
