In this interactive object, students use the Law of Sines to calculate forces.

In this interactive object, learners use the Pythagorean Theorem to calculate forces.

In this interactive object, learners use the Law of Cosines to calculate forces.

The target audience of this learning object is trigonometry students who have already learned what a radian is and have already derived the key values of the coordinates associated with common radian units, but now need to practice finding those values on the unit circle. The student does not need to know the definition of the six trig functions to do this activity.

In this learning activity you'll evaluate the six trig functions using a scientific calculator.

After a brief review, the student solves five practical shop problems using right angle trigonometry.

In this animated object, learners examine the operation of a Schmitt Trigger IC and its hysteresis function. A brief quiz completes the activity.

This screencast shows the symbols used to represent the type of pulse required at the clock input to activate flip-flops.

In this learning activity you'll evaluate the Sine, Cosine, and Tangent ratios of a right triangle.

In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).

A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.

Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.

Students use trigonometry to find the coordinates of the blending point where a line and an arc meet. Learners are given the coordinates of the center of the arc, the radius of the arc, and the direction of the line.

In this learning activity you'll explore the four stages of conflict (latent, triggering incident, conflict, new equilibrium) and then creates a similar diagram applying to a specific personal conflict.
