Ninth graders, after being given a unique scenario and a task sheet on Dead Man's Curve, calculate and explain the force needed to keep a car on a curve using a set of formulas and a geometric property of circles. They utilize and create...

In this geometry activity, students solve problems that are bimodal. They define properties of circles and triangles. There are 117 questions.

Students explore the interplay between the geometric and analytic information and on the use of calculus both to predict and to explain the observed local and global behavior of a function. They write a paragraph describing any...

Students use the given graph to sketch secant and tangent lines. The resource consists of an enlarged printable version of a graph available in PDF format.

Learners sketch the secant and tangent lines of a given graph. The resource includes an enlarged printable version of a graph available in PDF format.

This is a detailed site concerning tangent lines to curves. The site gives the limiting definition of the slope of the tangent. This site has a link to a discussion and animation of the approaching secant line, a java applet for the...

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to calculate angles formed outside a circle by tangent and secant lines.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students to solve for missing segments created by a tangent line and a secant line intersecting outside a circle.

Given examples of circles and the lines that intersect them, the student will use explorations and concrete models to formulate and test conjectures about the properties and relationships among the resulting segments.

A wealth of resources to supplement instruction on parts of the circle. Find lessons describing chords, tangents, secants, and segments, as well as related practice quizzes and classroom activities.

College professor Dan Bach reviews the basic calculus concepts of limits and derivatives. The site includes examples and animated graphs.

This lesson from the Hofstra University discusses the derivative. The lesson begins with the average rate of change of a function and discusses how this is related to the derivative of a function at a point. The site gives visual aids...

This document looks at look at the difference between averages and instantaneous rates of change. Formulas are provided for average speed, instantaneous speed, the slope of a secant line, the slope of a tangent, and the slope of a curve...

The resource investigates the graphical approach of calculating the derivative. Topics examined are secant and tangent lines. Students learn about the calculus concepts through notes and examples.

The resource examines the Mean Value Theorem. Students sketch secant and tangent lines. The graph is available in PDF format.
