Question

1 + tan square A upon 1 + cos squared equals to 1 minus tan A by 1 minus cot a is equal to tan square A

Answer 1

I hope you understood this

Answer 2

tan2A = (1 + tanA - sinA) (1 + cosA)

Given: 1 + tan2A/ (1 + cos2A) = (1 - tanA)/ (1 - cotA)

To Find: tan2A

Explanation:

1. We can multiply both sides with (1 + cos2A) and (1 - cotA).

2. After multiplication, we have 1 + tan2A = (1 - tanA)(1 + cos2A).

3. We can move the terms on the right side to the left side.

4. After simplification, we get tan2A = (1 - tanA)(1 + cos2A) - 1

5. We can simplify the expression further.

6. We get tan2A = (1 + tanA - sinA) (1 + cosA)

tan2A = (1 + tanA - sinA) (1 + cosA)
