Where can i find a degrees sing on this Calculator?
SOURCE: Sharp Scientific calculator EL-531D
you could try http://www.sharpusa.com/files/cal_man_EL531_509.pdf
this basically replaced the d model
or you could order one from:

You can access the .pdf manual for your particular calculator here:

Page 1 for how to set date/time:
“RATE SET”: To set the date, time, and tax rate, set this switch at the “RATE SET” position.
Date:
• Enter in the order of month, day and year, then press to complete the entry.
• Use to separate month, day, and year.
• When is pressed, the number entered is evaluated and displayed as “date” if the
value is within the following range; “Error” is displayed otherwise, and the previously set
date is restored.
Month: 1 - 12; day: 1 - 31; Year: 2000 - 2099 (in 4 digits) or 00 - 99 (in 2 digits)
Time:
• Enter in the order of hour, minutes, then press to complete the entry.
(There is no entry available for the seconds value. The clock starts at zero second.)
• If the hour/minute digit is less than 10, it is not necessary to enter the first digit “0”.
• Use to separate hour and minute values.
• When is pressed, the number entered is evaluated and displayed as “time” if the
value is within the following range; “Error” is displayed otherwise, and the previously set
time is restored.
Hour: 0 - 23 (24-hour system for the hour entry), Minute: 0 - 59

Hi,
The source of errors is most certainly due to the wrong schoice of angle unit (degree or radian). If the default angle unit set in your calculator is the degree, any value fed to the trigonometric functions (sin, cos, tan) is considered to be expressed in degrees. Consequently, if you calculate the arctangent ( tan^-1) of a value, the angle returend by that inverse trigonometric function is expressed implicitly in degrees.
Similarly if radian is the default angle unit in your calculator, any angle returned by an inverse trigonometric function (arcos, arcsin, arctan) is in radian.
Set the default angle unit as the one required by your problem at hand. This way, the angles returned will be in the right unit and you will not have a problem of interpretation.
Hope it helps.
