![]() They used a base 60 number system instead of base 10.Īs someone who surveyed for years, I used degrees of course. But it seems to me that the system of degrees (360 degrees in a full circle) comes from the Babylonian number system. What about between two adjacent seconds? Yikes!)Ĭorrect me if I am wrong. What values are between two adjacent minutes? 60 seconds. (What values are between 1 degree and 2 degree? 60 minutes. I'm thinking that it would be a nightmare to achieve the same continuity with degrees. This is when the inputs had to change from degrees to radians because it's easy to use the Real number line to model these changing angles over a continuous spectrum (domain). Each step is 1 degree.Īfter the development of the calculus (in the 17th century), it was realized that trigonometry could be used in dynamic situations, like periodic motion, where angles undergo change (smoothly and continuously). Somebody took one full rotation, and divided it up into 360 equal steps. When the ancient Greeks developed trigonometry (I think this word literally means something like "measurements of triangles"), it was for measuring static situations, like surveying, where angles do not change. Whether you are sitting at a school desk or holding a meeting, this free online scientific calculator can give you invaluable assistance.There are two interpretations for the trigonometric functions each lends itself to different applications. Besides being a useful tool that can save you plenty of time, it will save you money on buying a handheld device to carry around with you. One of the main advantages of this online scientific calc is that it’s absolutely free. ![]() It’s always ready for your use on any gadget with an Internet connection.
