finish. solve for ...
I have a basic Cal I related rates question and am unsure how to correctly solve. Can you check my solution? The part I'm a little confused about is where I differentiated both sides. Can you do as I did?
THanks for any help,
If two resistors of and are connected in parallel in an electric circuit to make an -ohm resister, the value of can be found from the equation:
If is decreasing at the rate of ohms/sec and is increasing at a rate of ohms/sec at what rate is changing when ohms and ohms
Substituing and gives that
Differentiating both sides with respect to time gives:
Substituting all known values into the above equation give:
Then we solve for to obtain the answer.
