Understanding the basic trigonometric functions of sine, cosine, and tangent are important for future problem solving in Physics. This Keynote Presentation demonstrates how to calculate the height of an object using one of the 3 basic trigonometric functions (the tangent function) and calculating the hypotenuse. The presentation can be used as teacher guided or instruction or independently by the student. Keynote gives the user the ability to voice-over the presentations. I have narrated present
