Answer:
b and d
Step-by-step explanation:
there is two answers
Pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos(60) in a triangle yields 1/2, and sin(60) yields (3^(1/2))/2. Thus, -pi/3, or -60 degrees would be a fourth quadrant point on the unit circle and these values would be negative as well, at cos(-pi/3)=-1/2 and sin(-pi/3)=-(3^(1/2))/2
Answer:
this doesn't even make sense.
Step-by-step explanation:
X = x
to solve, subtract both sides by x:
0 = 0
x is always equals to x so infinite solutions
