What is radians?
« on: March 29, 2008, 00:39:25 AM »
Arctan produces a number in radians. What exactly is radians? I was expecting degrees instead and i pop until i found out that atan result was in radians. :(

yes i know what arctan is. Is the opposite of tan where tan is sin/cos. But what is radians?

1 rad=360degree

Is this supposed to solve Supernova's question? or any other's question? ???

Instead of dividing the circle into 360 degrees, we divide it into Radians.
1 rad=360 degrees

So half a circle (180 degrees) = 0,5 radians.

Is just so easy.

radian, abr: rad:
2*π* rad = 360o=>
rad = 57°17′44.6″ (approximately)
