scientist watches a rocket rising vertically off the ground from a point that is 150 meters away on level ground. How fast is the rocket's angle of elevation increasing when the angle of elevation is 30 degrees if the rocket has attained a speed of 25m/sec at this time?
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.
