In Spanish. Interactive activities online on various geometric and trigonometric concepts such as area, perimeter, secants, tangents, etc. A terrific resource for students. Site is organized acoording to shape. (triangle, quadrilaterals,...

Three trig tables are provided for student and teacher reference. The first table lists the sine, cosine, tangent, secant, cosecant, and cotangent values of all whole-number angles from 0 to 90. The radian equivalent (to four decimals)...

Formulas and illustrations show the different kinds of angles created by intersecting tangents, secants, radii, and in combination.

In Spanish. This interactive unit seeks to familiarize you with the concepts of secant and tangent to a curve. You will be able to take a look at how the approximation is produced and understand the limit as a process that you can see...

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.

[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.

Learners explore the special angles for the six trigonometric functions. The special angles can be used to solve trigonometry problems. The table gives the values of sine, cosine, tangent, cotangent, secant, and cosecant for special angles.

In this activity, students use the calculator to solve trigonometry problems using sine, cosine, and tangent. They also find inverses of trigonometric functions.

In Spanish. This interactive unit could be used as a visual review of circles, circumference and tangents.

This Clark University trigonometry tutorial site features questions and answers about what students can learn from trigonometry.

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.

The Clark University site shows and explains the graphs of the six trigonometric functions. It explains how to find an arbitrary angle measurement using trig. Also, it explains that sine and cosine functions are complementary.

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

Several examples are presented that demonstrate how to graph the tan, cot, sec, and csc functions.

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...
