The subtangent at \(x=\pi / 2\) on the curve \(y=x\) \(\sin x\) is
- A 0
- B 1
- C \(\pi / 2\)
- D None of these
Answer & Solution
Correct Answer
(C) \(\pi / 2\)
Step-by-step Solution
Detailed explanation
Given, curve is \(y=x \sin x\) At \(\quad x=\frac{\pi}{2}\), we have \(y=\frac{\pi}{2}\) Slope of the tangent at \(x=\frac{\pi}{2}\) From Eq. (i), we get…
