Let and be the sides of two squares such that . The rate of change of area of the second square with respect to the area of the first square is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Area of the first square is A1=x2. Area of the second square is A2=y2=x-x22=x2+x4-2x3 So, the value dA2dA1=dA2dxdA1dx=2x+4x3-6x22x=1-3x+2x2
