Is this correct?

[Steven G]

Just a little nit-pick:

While specifying "unit" we do not use plural. Thus

units of dv/dt is volts/sec

Really?? But it is correct to say 620 volts/second??

By the way, your problem is a Calculus problem. Differential Equations is a course which you take after Calculus 3. Just because you are computing a derivative does not mean the topic is differential equations. ....................................[moved to correct forum]

No .... to be "technically" correct it should be 620 volt/sec. That avoids lot of head-ache later (in dimensional analysis where 'second' gets abbreviated as 's').

Really? Seriously, is this an engineering thing or do mathematicians agree with this?

It is for sure an "engineering thing" - mathematicians (which I am not one) may not care!

It's impossible to tell from that picture. Please post an image of the entire problem or even better write it out in LaTex.
