Q71.Consider the following statements P : Suman is brilliant Q : Suman is rich R : Suman is honest The negation of the statement "Suman is brilliant and dishonest if and only if Suman is rich" can be expressed as (1) ∼(Q ↔(P∧∼R)) (2) ∼Q ↔∼P ∧R (3) ∼(P∧∼R) ↔Q (4) ∼P ∧(Q ↔∼R)
What This Question Tests
This question tests the evaluation of a limit involving trigonometric functions and absolute values. It requires careful handling of the square root of a squared term, leading to different left-hand and right-hand limits.
Concepts Tested
Formulas Used
lim (x->0) sin(x)/x = 1
1 - cos(2θ) = 2sin^2(θ)
