The equation of the normal to the curve \(y=\sin x\) at \((0,0)\) is :

  1. A \(x-y=0\)
  2. B \(x+y=0\)
  3. C \(x=0\)
  4. D \(y=0\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(x+y=0\)

Step-by-step Solution

Detailed explanation

\(\frac{dy}{dx} = \cos x\) \(m_t = \cos(0) = 1\) \(m_n = -\frac{1}{m_t} = -1\) \(y - 0 = -1(x - 0)\) \(y = -x\) \(x + y = 0\)
