If dx = f(x) + A  n | x + | + C, then

f(x) = tan –1 x, A = –1

f(x) = tan –1 x, A = 1

f(x) = 2 tan –1 x , A = –1

f(x) = 2 tan –1 x, A = 1

Text Solution

Verified by Experts

The correct answer is:

Put x = tan θ ⇒ dx = sec 2 θ d θ

⇒ Ι = . = θ = θ sec θ –  n |sec θ + tan θ | + C

= tan –1 x – log + C
