Question

( g>left(0+frac{1}{sqrt{x^{2}-1}}right. )
( quad quad ) put ( quad x=sec theta )
( theta=sec ^{-1} x )
z) ( frac{c o t^{-1} cdot 1}{sqrt{s e c^{2} theta}} )
( cot ^{p} frac{1}{tan theta} )
( =frac{omega+1}{=} frac{c 0+0}{0} )
( =sec ^{-1} x )

# Column B Column A (i) 24 The simplest form of cot-1 (2),1x1 > 1 Q.5. Let A = {1, 2, 3). Then, the number of relations containing (1, 2) and (1, 3) which are reflexive and symmetric but not transitive is (ii) sec-1x Q.6. The total number of injective mappings from the set containing 3 elements into the set containing 4 elements is
