Question
Statement1: Number of ordered pairs (
, x) satisfying 2sin = ex + ex, [0, 3θ] is 2.
Statement2: Number of values of x for which sin2x + cos4x = 2 is zero.
- Statement1 is True, Statement2 is True; Statement2 is a correct explanation for Statement1
- Statement1 is True, Statement2 is Tue; Statement2 is NOT a correct explanation for Statement1.
- Statement1 is True, Statement2 is False
- Statement 1 is False, statement2 is True.
The correct answer is: Statement1 is True, Statement2 is Tue; Statement2 is NOT a correct explanation for Statement1.
B) is the correct option
st(1) LHS 2, RHS 2 sin = 1
= /2, 5/2 & x = 0
ordered pairs are (/2, 0)
and (5/2, 0)
St(2) sin2x = 1 and cos4x = 1
both are not possible for same x.
