If \(y=f(x)\) is a curve and if there exists two points
\(A\left(x_{1}, f\left(x_{1}\right)\right)\) and \(\mathrm{B}\left(x_{2}, f\left(x_{2}\right)\right)\) on it such that \(f^{\prime}\left(x_{1}\right)=-\frac{1}{f^{\prime}\left(x_{2}\right)}=\frac{f\left(x_{2}\right)-f\left(x_{1}\right)}{x_{2}-x_{1}}\) then the tangent at \(x_{1}\)1 is normal at \(x_{2}\) for that curve.
Number of such lines on the curve y = sinx is
  1. 1
  2. 0
  3. 2
  4. infinite
