These Facts Allow You To Calculate The Tangent And The Sine And So Forth Of Certain Angles Without Actually Doing Any Measurement. For Example, Suppose Your Angle Theta Is 45 Degrees. Trigonometry Was Probably Invented For The Purposes Of Astronomy. The Origins Of Trigonometry Can Be Traced To The Civilizations Of Ancient Egypt, Mesopotamia And The Indus Valley, More Than 4000 Years Ago. The Common Practice Of Measuring Angles In Degrees, Minutes And Seconds Comes From The Babylonian's Base Sixty System Of Numeration. There Are 60 Seconds In A Minute, 60 Minutes In A Degree, And 3600 Seconds (60 X 60) In A Degree. 14 Minutes 51 Seconds Equals 891 Seconds, Which Is 891/3600 Of A Degree Or.2475 Degree. For Simplicity, Let's Call That ¼ Of A Degree. Therefore, The Angle In Question Is 63¼ Degrees. There Are 360 Degrees In One Revolution. Degrees Can Be Subdivided, Too. One Degree Is Equal To 60 Minutes, And One Minute Is Equal To 60 Seconds. Therefore, An Angle Whose Measure Is One Second Has A Measure Of Degrees. Angle Units " Q Enter DMS (Degrees/Minutes/Seconds) Values As D.MMSSs, Using 0s As Necessary: Degrees (0–7 Digits) Decimal-point Separator Minutes (must Be 2 Digits) Seconds (must Be 2 Digits) Fractional Part Of A Second For Example, Enter 48¡5'3.5" As 48.05035.
