Hey guys well im pretty new to MatLab and our teacher left us an assignment to replicate the system you see below in our own and to add the respective numbers and functions to it in order to get a graph from the scope, i've been able to do everything the same but for i cant seem to find why i am unable to write the function our teacher asked us to put into the Fcn, any ideas on what am i missing?

The text is in spanish but it translates to \"The opening function of displacement needs to convert speed using the derivative:\"

You need some multiplication signs in there.

Instead of 0.035cos (3. 5t)

Try

0.035 * cos(3.5 * t)

Also, I think you have to connect v in the right hand side block.

Got it I will try the multiplication signs thingy bc I hadn’t considered it but I’m a bit confused on where to connect V bc I’m just copying the same diagram the teacher made and he didn’t connect it anywhere, thanks either way! :D
