cos3x + sin(2x- (7pi)/6)=-2

Find x cos3x+sin(2x-(7 pi)/(6))=-2

Find the period of cos x sin (x - (2pi)/(3))

If "cos 3x + "sin" (2x - (7pi)/(6)) =-2 , then x =

If "cos 3x + "sin" (2x - (7pi)/(6)) =-2 , then x =

If cos 3 x + sin (2 x - (7 pi)/(6)) = - 2 then x is equal to (k in Z)

If cos3x+sin(2x-(7 pi)/(6))=-2, then x is equal to (k in Z)(pi)/(3)(6k+1)( b) (pi)/(3)(6k-1)(pi)/(3)(2k+1)( d ) none of these

If cos3x+sin(2x-(7pi)/6)=-2 , then show that x is of the form π / 3(6m+1) .

If cos3x+sin(2x-(7pi)/6)=-2 , then show that x is of the form π / 3(6n+1) .
