Our tangent calculator accepts input in degrees or radians, so assuming the angle is known, just type it in and press "calculate". Easy as that. If the angle is unknown, but the lengths of the opposite and adjacent side in a right-angled triangle are known, then the tangent can be calculated from these two measurements.
The tangent function is used in measuring height of objects located at known distances and has application in flight path and altitude gain calculations.
In engineering, it is used to calculate forces of supporting structures, like roof beams. They are also used in robotics to calculate robot arm kinematics. It is more true when the spread of angles is relatively low, as in an SRB pavilion where the mains and break angles are typically cut within several degrees of each other. However, as you can see in its graph below the tangent function is not linear. As the spread between the lowest and highest pavilion or crown angles increases as is typical with more complex designs, the practice of adding a constant difference to the angles breaks down and the results diverge from a tangent ratio conversion.
This can cause noticeable deviations in the planview and may also have ramifications for meet points. The table presented adjacent to the graph illustrates a case of this divergence. Note that as the angle approaches 90 degrees the value of its tangent increases without bound. However, most of the time you will probably be most concerned with pavilion or crown mains facet angles and employ those for the reference angles when you are doing tangent ratio conversions.
You might want to change the angles on the crown as well as the pavilion when you are converting the angles on a design to cut it in materials of different refractive indexes. Or you might not… If you do want to lower or raise the crown angles, that gets done as a separate and independent conversion from changes you might also be making to the pavilion angles.
Algorithm wise, the conversion process is blind as to whether the angles you input are on the pavilion or crown or something else altogether.
So in the circumstance where you wanted to convert both a crown and pavilion using the same tangent ratio you could do this in a single pass with the converter. The really good news is that Internet servers can be custom programmed to perform tangent ratio conversions too…. Summary of Some Key Fundamental Concepts.

The really good news is that Internet servers can be custom programmed to perform tangent ratio conversions too… Summary of Some Key Fundamental Concepts Tangent ratio conversion is a mathematical procedure for changing the elevation angles of the facets on the pavilion or crown of a gemstone design without altering their respective plan views. Tangent ratio conversion can be used to both lower or raise angles as desired.
If her height is 5 feet, how tall is the monument? The horizontal distance is denoted by BC which is 25 feet. We can find the height of the monument by first using the tan formula and then adding the height of the student. Adding the height of the student gives us the height of the monument AD. Answer: For using the series expansion, the angle x must be converted to radians. Tangent Calculator. Result: tan X : 0. What is tan?
Angle x in degrees Angle x in radians tan x. Quadrant x in degrees x in radians Sign of the tan function.
