On a coordinate plane, a hyperbola has curves in quadrant 1 and 3. The curve in quadrant 1 opens up and to the right and approaches the positive y-axis and positive x-axis. The curve in quadrant 4 opens down and to the left and approaches the negative x-axis and negative y-axis.

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

a.)the line for function b is steeper
