Question

Q2. Find the other trigonometric functions: If and 180° < θ <
270°.​

Answer 1

Since 180° < θ < 270°, θ lies in the third quadrant.

We have cos θ =

We have cos θ ===∴ sin θ =

∴ sin θ =

∴ cosec θ = θ

sec θ = θ

tan θ = θ θ

Since 180° < θ < 270°, θ lies in the third quadrant.

• We have cos θ =

• =

• =

• ∴ sin θ =

• ∴ sin θ =

• ∴ cosec θ = θ

• sec θ = θ

• tan θ = θ θ
