Please please solve accurate.




I will rate it up if you solve accurate. Thanks

Extracted text: (ii) The voltage across a charging capacitive circuit is described by the following equation: V(t) = 10(1 - e 2) Determine the rate of change of V(t) at t=2seconds. (iii) The instantaneous power associated with a cutting device is given by the following circular equation: P(t) = 20Sin(100 trt)Cos(100Trt) Determine the rate of change of P(t) at t-1second.
