Javascript math problem

[stathis30_2000]

Hi all,

I am facing a very strange problem concerning javascript math functions ..
I need to calculate the cos,sin values of some angles .When I try Math.cos(0) I get result =1 which is correct. When I try Math.cos(180) I get result=-0.59 ! As fas as I remember cos(180) = -1 ... Why is that happening??

Please help me, is urgent.

Thanks
ST

Hi,

I think you have to call the cos-Method with the radian instead of the angle.

result = Math.cos(yourAngleVal * Math.PI/180)
.. should work!
