A ball is being launched into the air. 21 feet away from the launch site is a camera. If the ball is travelling vertically at 13 feet per second, what is the rate of change of the angle of elevation from the camera to the ball when the ball is 41 feet off the ground? (Do not include units in your answer, and round to the nearest hundredth.)
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.
