Find cos 32° 45'
Hello,
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')
you press
[COS] 32[DMS]45 [DMS] ) and press [=] The result si 0.841039013
Hope it helps.
