Looking to go back to complete basics on how some aspects of Simulink work and am running into something mathematically that seems off. I've made a simple program with blocks (sine wave)->(1/s)->(Scope) with an additional scope set up to view the initial sine wave. I've set the amplitude of the sin wave to 1 and run the program. The sine wave plot looks correct, ±1 amplitude and the wave starts at (0,0), like a normal sine wave. The integral of a sine wave is -cos, so I expect to see a wave that runs ±1 and starts at (0,1), but what simulink outputs is a sine wave that starts at (0,0) and the amplitude runs from 0 - 2, not ±1. Am I missing something on how to set up a signal to be integrated? If I use the derivative function, I do get a cos wave. Any thoughts?
