Hi! I'm learning about solving transient circuits using the differential method and step-by-step approach and I'm just wondering if there's any advantages or disadvantages to both. Are there any problems which will be easier solved using the step-by-step approach vs differential? Thanks!

For ex, say you were rolling a ball down a steep ramp (about 85-90 degrees to horizontal, so almost straight). The ramp is say at least 100m long so there's enough time for the ball to build up velocity, etc. Is it possible for any circumstances to happen where the ball would temporarily...

I've been reading about Hubble Space Telescope and the concept of momentum dumping done by the magnetic torque rods. I understand that when the reaction/momentum wheels are saturated, the magnetic torquers (magnetorques/magnetic torque rods, there were a lot of names for them !) must be used to...
