solve `sin((5pi)/(6)+x)+sin((5pi)/(6)-x)`

What is the values of tan ((5pi)/(6))sin((7pi)/(6)) ?

Evaluate: int(cos x)/(sin(x-(pi)/(6))sin(x+(pi)/(6)))dx

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

int(sin(2x))/(sin(x+(pi)/(6))sin(x-(pi)/(6)))dx

Prove that the value of each the following determinants is zero: sin^(2)(x+(3 pi)/(2))quad sin^(2)(x+(5 pi)/(2))quad sin^(2)(x+(7 pi)/(2))sin(x+(3 pi)/(2))quad sin(x+(5 pi)/(2))quad sin(x+(7 pi)/(2))sin(x-(3 pi)/(2))quad sin(x-(5 pi)/(2))quad sin(x-(7 pi)/(2))

sin ((pi) / (5)) sin ((2 pi) / (5)) sin ((3 pi) / (5)) sin ((4 pi) / (5)) =

Maximum value of sin (x + (pi)/(6)) + cos (x + (pi)/(6)) is

Let f(x)=sin[(pi)/(6)sin((pi)/(2)sin x)] for all x in R

The value of sin ""(pi)/(16) sin ""(3pi)/(16) sin ""(5pi)/(16) sin ""(7pi)/(16) is

The solution set of x in(-pi,pi) for the inequality sin2x+1<=cos x+2sin x is: x in[0,(pi)/(6)]( b) x in[(pi)/(6),(5 pi)/(6)]uu{0}x in[-(pi)/(6),(6 pi)/(6)] (d) None of these
