Let’s say you’re on top of a cliff, which drops vertically 150m to the ocean below. You throw a ball with an initial speed of 8.40m/s at an angle of 20 above the horizontal. About how many meters is it from the base of the cliff to the point of impact? Use g=9.806m/s2 for gravity.
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.
