Answer 1

Answer:

4)B,C,A

step by step explanation:

We straight away see that tan2 < 0 because

2

Π

<2<Π

but tan1 > 0 because 0 < 1 <

2

Π

and tan3 < 0 because

2

Π

<3<Π

now tan3−tan2=

cos3

sin3

−

cos2

sin2

=

cos3cos2

sin3cos2−cos3sin2

=

cos3cos2

sin1

>0

because sin1>0 andcos3<0 and cos2<0 because

2

Π

<2,3<Π

so tan1>tan3>tan2
