Rad to Deg

Hello,
How can I transfert a Rad number to deg?

Thanks for any help.

deg=rad*57.295779513082320876798154814105

the constant is 180/pi

Multiply it by 360/2pi.

(That's probably what Ked said, but I can't see it!)

Test: 2pi rad = 2pi * 360 / 2pi = 360. OK

pi/4 rad = pi/4 * 360 / 2pi = 360/8 = 45. OK

:eek: How do u know that he responded?? How does this ignore thing work.. dont explain here and ruin the thread ... maybe answer in ur ignore thread... i am confused... more than usual :eek:

And just so that i am not accused of chit chatting...

You are both right it is 180 / pi ;)

noooooooo...
to convert to degree you have to multiply the angle in radian by

90/ (pi/2)

:D :D :D

OMG :D I think it's rather (2*Srt(45/pi))^2 :rolleyes: ;)

Or, more precisely:

180/SqrRoot[6*Sum{n = 1 to Infinity}(n^(-2))]

:)
