Question

The value of 9 sec²A - 9 tan? A is equal
土 +​

Answer 1

Answer:

9.

Step-by-step explanation:

9 sec^2 A - 9 tan^2 A

9 (1 + tan^2 A) - 9 tan^2 A

[ since sec^2 A - tan^2 A = 1

so sec^2 A = 1 + tan^2 A ]

9 + 9 tan^2 A - 9 tan^2 A

[ here + 9 tan^2 A and - 9 tan^2 A will get cancelled ]

so the final answer is 9.
