The variable `x`satisfying the equation `|sinxcosx|+sqrt(2+tan^2+cot^2x)=sqrt(3)`belongs to the interval`[0,pi/3]`(b) `(pi/3,pi/3)`(c) `[(3pi)/4,pi]`(d) none-existentA. `[0,pi/3]`B. `(pi/3pi/2)`C. `[(3pi)/4,pi)`D. None of these

Answer» Correct Answer - D
`abs(sinxcosx)+abs(tanx+cotx)=sqrt3`
`or abs(sinxcosx)+1/abs(sinxcosx)=sqrt3`
But `abs(sinxcosx)+1/(abs(sinxcosx))ge2`
hence, no solution.
