Which statement is correct? A. Secant is the reciprocal of tangent.
B. Cosine is the reciprocal of cosecant.
C. Cotangent is the reciprocal of secant.
D. Cosecant is the reciprocal of sine.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
