Question

Match the following:

Column I	Column II
(A) lim(x →1/√2) (x - cos(sin-1x))/(1 - tan(sin-1x)) is equal to	(p) Does not exist
(B) If f(x) = logx2(logx), then f'(1/2) is equal to	(q) - 1/√2
(C) For the function f(x) = ln tan(π/4 + x/2) if dy/dx = secx + p, then p is equal to	(r) 28
(D) lim(x →0) 1/x√((1 - cos2x)/(1 + cos2x)) is equal to	(s) 1
	(t) 0

Answer 1

Answer is (A) → (q), (B) → (p), (C) → (t), (D) → (p)
