You just took off in your trusty Lockheed SR-71. It's a fine windless day. Your instruments indicate a true air speed (speed relative to the surrounding air) of 400 miles per hour and a climb rate (vertical speed) of 10,000 feet per minute. You figure that your flight path makes an angle of degrees with the horizontal. (Enter a mathematical expression or a decimal approximation with at least one digit beyond the decimal point.) Hint: Draw a triangle showing your ascent and the distance along your flight path that you travel in one minute. Apply an inverse trig function.
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.
