How to correctly get a sine/cosine-signal in Simulink?

I have already set a angle-signal in simulink, then i want to get the sine- and cosine-signal of this angle. I have tried two ways to get this signal (SinCos-Block and Matlab Function). But they were both strange and wrong. I'll put the pictures of angle-signals and results below. The first is original angle-signal and the second is Cosine-signal. How to correctly get the sine/cosine-signal in Simulink? Thx for ur help!

Are you sure it is wrong? Your angle changes fairly fast, which is why the cosine also changes fast. The input for the Cosine block is in radians.

Thanks for your help. If I make a Matlab-Function, which "y = cos(u)" is, the input also must be in radians?
