Given information
From part 48a, the given curve equation is .
The objective is to tell In view of part (b), what can you say about the expression for that you found in part (a).
Step-by-step explanation
Step 1.
From part (b) we have,
Notice that the radicand is always negative, it cannot be positive for any x, so, the radical does not give the real solutions.
As the function is imaginary, we can assume that the derivative is only valid for imaginary values also.
