Answer 1

Answer:

0 is the required answer.

Step-by-step explanation:

1. Remember following formulas :

• sin(90° - ∅) = cos∅
• sec(90° - ∅) = cosec∅
• cot(90° - ∅) = tan∅
• cot∅ tan∅ = 1
• sec∅ cos∅ = 1
• sin∅ cosec∅ = 1

2. Apply the above formulas obtain the values.

3. Since question was big so I broke it into 3 parts.

4. Solve each part and then substitute final values at last.

→ After solving the last step we get evaluated value for whole sum.
