You must first set angle unit to degree.
Press the [MODE] key a certain number of times until you get to a screen that displays Deg Rad Grad. Press number key 1 to select degree.
Once this is done you can calculate trigonometric functions. To enter angles in DMS you have a key marked with degree symbol, a quotation mark, and a double quotation mark. In what follows that key is represented as DMS.
To calculate cos(30 deg 24')
[COS] 30 [DMS] 24[DMS] [=]
If you get an error message you will have to enter the seconds even if the value is 0

SOURCE: Find cos 32° 45'
Look at the column of keys under the ALPHA key. You have the integral, the square root, and then the key that has a degree sign, an apostrophe and a double closing quotation mark. That is the one you use to enter the angle in sexagesimal notation. To simplify my task I will symbolize the key with [DMS], degree, minute , second.
To calculate cos (32° 45')
[COS] 32[DMS]45 [DMS] ) and press [=] The result si 0.841039013
Hope it helps.
