A Zenith Angle is the angle between a given point on Earth's surface and the vertical line that passes through the same point. It is measured from 0° at the horizon to 90° at the point directly above (the zenith).
Calculating Zenith Angles is important in many fields, such as astronomy, geography, and surveying. It can help determine the height of objects, the position of celestial bodies, and the location of points on Earth's surface.
To convert a Zenith Angle to degrees, simply subtract it from 90°. For example, a Zenith Angle of 45° would be equivalent to 90° - 45° = 45° in degrees.
Some calculators may have a built-in function for calculating Zenith Angles, but it is not a common feature. However, most scientific or graphing calculators have trigonometric functions (such as sine, cosine, and tangent) that can be used to calculate Zenith Angles.
To input a Zenith Angle into your calculator, first make sure it is set to the correct mode (degrees or radians). Then, use the appropriate trigonometric function (e.g. sine, cosine, tangent) with the Zenith Angle as the input value. Make sure to double-check your calculator's user manual for specific instructions on inputting values.
