Then, which of the following is correct?
- A (a)
- B (b)
- C (c)
- D (d)
Answer & Solution
Correct Answer
(C) (c)
Step-by-step Solution
Detailed explanation
A. Equation of tangent is \(y y_1-2\left(x+x_1\right)=0\) So, \(\quad \sqrt{8} y=2(x+2 \Rightarrow \sqrt{8} y=2 x+4\) \( \begin{aligned} \Rightarrow & 2 \sqrt{2} y & =2 x+4 \\ \Rightarrow & -\sqrt{2} y+x+2 & =0 \end{aligned} \) B. Equation of normal is \(y=m x-2 a m-a m^3\)…
