Answer 2

Answer:

ird quadrant.

We have cos θ =

-35

Now, sin2θ + cos2θ = 1

∴ sin2θ = 1 – cos2θ =

1-(-35)2

=

1-925

=

1625

∴ sin θ =

±45

But θ lies in the third quadrant.

∴ sin θ is negative.

∴ sin θ =

-45

∴ cosec θ =

θ

1sinθ=1(-45)=-54

sec θ =

θ

1cosθ=1(-35)=-53

tan θ =

θ

θ

sinθcosθ=(-45)(-35)=43

cot θ =

θ

1tanθ=1(43)=34
