If the system of linear equations , has a non-trivial solution then the values of are
detailed solution
Correct option is B
Given equations have non zero solution ⇒sin3θ−11cos2θ43277=0⇒(sin3θ)(28−21)−(cos2θ)(−7−7)+2(−3−4)=0⇒sin3θ+2cos2θ−2=0⇒3sinθ−4sin3θ+21−2sin2θ=2⇒3sinθ−4sin2θ−4sin3θ=0⇒−sinθ4sin2θ+4sinθ−3=0⇒sinθ(2sinθ+3)(2sinθ−1)=0⇒sinθ=0 or sinθ=1/2⇒θ=nπ or θ=nπ+(−1)nπ/6,n∈ZSimilar Questions
