Introduction to Trigonometry [ River Example ]

In this experiment, you will learn how to measure distances using simple math. By looking down from an elevator at a red car across the river, you create an invisible right triangle. You can drag the elevator to change your height or move the car to change the distance. By using trigonometric ratios like Sine, Cosine, and Tangent, you can calculate the width of the river without ever needing to cross it. It is a great way to see how math helps us solve real world problems in engineering and navigation.
