Seventh graders investigate the concept of functions and how they are used in the context of the real world while identifying the dependent and independent variables. They graph relations and functions and find the zeros of functions....

Students explore the concept of finding the composition of seawater.  In this finding the composition of seawater instructional activity, students make a saturated salt water solution.  Students discuss why there is variation...

In this calculus worksheet, students assess their understanding and knowledge of limits, derivatives, differential equations, and other calculus topics.  The one page worksheet contains twenty-eight multiple choice questions. ...

Students solve problems with triangles. In this geometry lesson, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.

Use this site to find the formula for the line vector of a field on a curve. Also included is the formula for complex plane circumstances. Read further down the page for higher math involving involveing Poincare's

Provides details about the properties of straight lines, types of straight lines, line segments, rays, curved lines, and types of angles.

This site provides information on tangent lines and parametric curves. It includes formulas and examples.

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.] Students watch a video and attempt practice problems on counting lines and curves in various two dimensional shapes.

In this lesson, students receive raw data to construct a Lorenz Curve and calculate the Gini Coefficient. This lesson prepares AP Microeconomics students for the Advanced Placement exam. The teacher will briefly interpret the Gini...

This CoolMath resource provides instruction and practice for tangent lines.

This website describes what a Lorenz curve is, and shows what it would look like graphically. A mathematical formula is also given.

The Northeast Parallel Architectures Center at Syracuse University offers a fairly detailed site explaining the slope of a tangent line to a curve.

Students plot points then use regression lines to design a vehicle.

This site give the formula for finding the slope of the tangent line to a polar graph. The page offers step by step explanations and worked examples.

Glossary of terms that contains gini coefficient and lorenz curve. Both definitions contain a clear graph, scroll down to the L's to find lorenz curve.

This site describes lines and angles "as found in various plane (flat) geometric figures.".

[Free Registration/Login may be required to access all resource tools.] Calculate the equation of a line tangent to a single point

In this activity, students use the CellSheet Application to approximate the slope of a line tangent to a curve.

E learning text offers information on measuring income distribution with the Lorenz Curve. Site presents charts and data for one to use in order to construct or analyze a Lorenz Curve.

[Free Registration/Login may be required to access all resource tools.] The video shows how to count the number of straight lines and curves in a given 2D figure. The video is followed by practice problems.

Exponential graphs increase rapidly in the Y direction and will never fall below the X -axis, thus forming a curve.

The tangent to a curve is always found at a certain point along the curve. Often you will be asked to find the normal to a curve at a point. View an example on this site.

This page goes over what regression method is and how a regression line fits in. Dr. MAth also suggests a book on regression if you are interested.
