Answer:
P ( 3, - pi/3 + 2 pi n) or P ( -3 , -pi/3 + pi(2 n +1))
Step-by-step explanation:
P ( 3, - pi/3)
We can circle 2pi n around the circle and be back at the same polar coordinate
P ( 3, - pi/3 + 2 pi n)
or we can flip the radius to a negative and add pi to the theta
P ( -3, - pi/3 + pi)
Then we can circle 2pi n around the circle and be back at the same polar coordinate
P ( -3 , -pi/3 + 2 pi n +pi)
P ( -3 , -pi/3 + pi(2 n +1))
Answer:
Below.
Step-by-step explanation:
So calculate.
-1/6x+3+1/3x+1=x+4.
Cancel equal terms.
-1/6x+4+1/3x=x+4
Multiply both sides -1/6x+1/3x=x
collect like terms.
-x+2x=6x
move the variable from right to left.
x=6x
collect like terms
x-6x=0
Divide both sides
-5x=0
x=0
