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

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) .

If cos3x+sin(2x-(7pi)/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

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

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

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

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

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

Range of 3cos x+5sin(x-(pi)/(6)) is

lim_ (x rarr (pi) / (6)) (2 (sin x cos ((pi) / (6)) - cos x sin ((pi) / (6)))) / (x- (pi) / (6))
