Simulink

I integrate a sin function with an initial condition -1, through the simulink integrator block, and the result is like a cosine waveform with a peak upper than 1(almost 6), when the sine has an amplitude of 1. why?

Good question, I don't see that behaviour with:

Sin ---> 1/s ---> Scope

What are your simulation settings? solver and step?
