Please Solve Now 1. secθ×sinθ 2. cscθ×cosθ

3. tanθ×cscθ 4. cotθ×secθ

5. 1-cos²θ 6. sec²θ-1

7. csc²θ-cot²θ 8. 1-sin²θ

Step-by-step explanation:

1, sec theta  * sin theta = 1/cos * sin = sin/cos =tan theta

2. cosec theta * cos theta = 1/ sin * cos = cos/sin = cot theta

3, tan theta * cosec theta =sin/cos * 1/sin = 1/cos

4, cot theta * sec theta = cos /sin * 1/cos= 1/sin

5, 1 - cos^2 theta = sin ^2 theta

6, sec^2 theta - 1 =tan ^2 theta

7 , cosec^2 theta - cot^2 theta = 1

8, 1 - sin^2 theta = cos^2
