A projectile is launched from the ground at an angle of thetaθ above the horizontal with an initial speed of v in ft/s. The range (the total distance traveled by the projectile over level ground) of the projectile is approximated by the equation x = v^2/32 sin 2 theta. Find the launch angle of a projectile with an initial speed of150ft/s and a range of 170 ft. I get 8 degrees but not the second value.
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.
