Complete the following fundamental identities:

Question

1. Reciprocal Identity: csc (A) = 

2. Reciprocal Identity: cot (A) =

3. Ratio Identity: cot (A) = 

4. Pythagorean Identity = 1 - cos^2(A) =

5. Pythagorean Identity = 1 +tan^2(A) =

Answer 1

Csc A = 1 / sin A

 

Cot A = 1 / tan A

 

Cot A = Cos A / Sin A

 

1- cos^2 A = Sin^2 A

 

1 + tan^2 A = sec^2 A
