Question

prove that (1+tan square A) (1+sina)(1-sina)=1

Answer 1

L.H.S

(1+tan²A)(1+sinA)(1-sinA),

sec²A (1-sin²A),

1/cos²A × cos²A,

1,

hence

L.H.S=R.H.S

Answer 2

Answer:

L.H.S =(1+tan²A)(1+sinA)(1-sinA),

sec²A (1-sin²A),

1/cos²A × cos²A,

1,

Hence ,

L.H.S=R.H.S

This is your answer.

Hope this helps you!
