Suppose you have two calculators, one set to work in degrees, and the other set to work in radians. The trouble, is that you don't know which is which. When you enter cos(3.14) you get -0.999999 from the first calculator, and 0.998499 from the second.

Explain how you could tell, without further use of a calculator, which one is set to degrees and which is set to radians.

anonymous · Answer

the first one is the degrees because degrees can be both positive and negative... thats just a guess.

anonymous · Answer

first one is set to radians becaue cos (3.14 radians) is negative.  cos (3.14 degrees) is positive. so the second one is set to degrees.

what do i know? lol
