I think the trick is to add the two middle terms together. (And the 2 end terms).
8 - 12x
The variable is x. The coefficient is - 12.
8 is a constant.
The coefficient always goes with a variable.
3x^2 + 2x + 5
Nothing can be combined. The leading coefficient is 3 (which goes with the greatest power of the variable x^2 in this case) and the other coefficient is 2. 5 is a constant.
You can go full 2π rotate around counterclockwise so the angle wouldn't be negative.
So -π/2 + 2π = -π/2 + 4π/2 = 3π/2
So (4, 3π/2) is the same point as (4, -π/2)
Answer:
im pretty sure its 67, sorry if I'm wrong
