In the modern era, the most notable depiction of the eye is the reverse of the Great Seal of the United States, which appears on the United States one-dollar bill.he Eye appears on the following currency: 1  United States one-dollar bill, as part of the Great Seal (see above). 2  The 50 Estonian krooni note, as part of a depiction of the pipe organ of the Kaeina kÃ¤ina. 3  Church the 500 ukrainian hryvnia.  note
Also, be sure to note the month and time of day. To calculate the sun's angle, divide the length of the stick by the length of the shadow. Next, find the inverse tangent of that value - use tan^-1 for the inverse tangent. If using a scientific calculator, be sure that it is set to degrees and not radians. Repeating the above experiment multiple times a day, over a course of time, eventually yields a table of sun angle values.
The azimuth angle indicates the direction of the sun in the horizontal plain from a given location. North is defined to have an azimuth of 0Â° and south has an azimuth of 180Â°. The various trajectories of the sunâs in the sky are bounded by those of the 21st day (solstice) of each month from December 21 until June 21.We plot the time, on the hour, for all hours during which the sun is in the chart.orth is defined to have an azimuth of 0Â° and south has an azimuth of 180Â°.
