$\sin^{-1}(\frac{1+x^2}{2x})$ is |
continuous but not differentiable at x = 1 differentiable at x = 1 neither continuous nor differentiable at x = 1 continuous everywhere |
neither continuous nor differentiable at x = 1 |
$\sin^{-1}(\frac{1+x^2}{2x})$ is defined only for x = – 1 and x = 1. Hence (C) is the correct answer. |
