After a brief review, the student solves five practical shop problems using right angle trigonometry.
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.
You'll answer a list of questions based on their gender then answer the same questions as if you were born the opposite gender.

In this animated and interactive object, learners examine the voltages that develop across two series zener diodes, which are connected in opposite directions, when DC and AC voltages are applied across them. A brief quiz completes the activity.
In this learning activity you'll apply the Law of Sines in the solution on an oblique triangle when provided with two angles and the side opposite one of the angles.
