A boy is flying a drone at a constant height of 28 m above the ground. If the drone is moving horizontally, away from the boy, at a rate of 18 m/s, at what rate is the angle of depression from the drone to the boy’s location on the ground changing when the distance between the drone and the boy’s location on the ground is 53 m?
Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
