Solution: csc stands for cosecant
csc (2n+1) x 180˚
= Csc (360n +180)
= csc (180) and the csc has a period of 360˚
= 1/ sin (180)
As sin 180 = 0 so,
csc ((2n+1) x 180 degrees) is undefined as 1/0 is undefined when you calculate it in the calculator.
This is even function because
1)the ends are looking in one side, both are up
2)You can see that it has line symmetry y
3) for any point
f(x)=f(-x)
f(1)=-6
f(-1)=-6
23.8% of 164 is 39.032 so minus that off of 164 and you would've sold 124.968 cars and im guessing you should round so the dealership would've sold 125 cars.
Hmph...
