is there a way to use sin on degrees not radians ?

like:

sin(90) = 1 sin(0) = 0 sin(30) = 0.5

cos(90) = 0 cos(0) = 1 cos(30) = 0.8660254037844386467637231707529361834714

and so on...

math.rad?

[karlis]

math.deg()

math.rad()

these 2 functions converts between radians and degrees.

and where should i write it and how?

i do like this before:

math.deg(math.sin(90)) = 51.222236633301

math.sin(math.deg(90)) = -0.95407978866971

how?

[H!tman]

oh i find it lol

thanks

[Aibo]

math.sin(math.rad(90))

(my bad, i wrote math.deg at first)
