Sine, Cosine, Tangent
- Dr. Doug Davis, 3D
Your goal is to identify the trigonometric function that would be the red dashed line divided by the solid green line for the angle with the green arc. You should be able to identify 20 triangles in 2 minutes. Just select the trigonometric function to get started. When you get 20 correct answers or the time exceeds 2 minutes the result will show your time and number of correct and incorrect answers. If you select a wrong button, the correct button will highlight in green. You can pause the time display, but the result summary will show the actual time used.
