Question

Please can someone explain me the concept of derivatives when comes to "with respect to x" or "with respect to t" I got so confused. I understand that derivative of 2x is 2 and just that.

Answer 1

LIke this dv/dt <- I'm confuse what is that. Velocity with Respect to time? Or what. So what about it.. Something like that.

Answer 2

(first) Derivative of a function it just the slope of the function, which it expressed as change in y/change in x.
