> Mathematica needs to "remember" that expression so that it can recalculate it when s or t change, so it can't just automatically compute it [...] So, you change s and Mathematica looks at Plot[T, {r, 0, R}] and says, "nothing to do here", because...
I need to create a block that generates a boolean constant for a given time on detecting an instantaneous boolean pulse. I have no idea where to start. Pease help. Thanks.
Hi! I need help regarding modifying the NOR block. I have been trying to achieve a NOR block such that when I input all 0's in it, it gives me a 1 for 5 seconds, and then reverts back to 0. Here's how I have modified the NOR block so far: ...
I want to use the output of Dynamic[x] in a further computation. Here's a simple version of what I am trying to accomplish: Input: a = Dynamic[5] Output: 5 Input: a + 3 Output: 8 Here's whats I actually get: Input: a = Dynamic[5] ...

I am trying to build a magnetic tachometer using SystemModeler and Arduino. I am using the basic sensor example of ModelPlug with the potentiometer replaced by a Hall Effect sensor. So far, I have been able to generate interrupts (pluses)...
Thank you for your help. I am happy to report any bugs. FYI, I am using windows 7.
If you buy Mathematica, do you still have to pay $5 per month - as you do for wolfram-alpha - in order to access more than three step-by-step solutions per day?
