Question

Find out the value of 9 sec square A - 9 tan square A

Answer 1

9 sec2 A - 9 tan2 A
= 9( sec2 A - tan2 A)
= 9 × 1
= 9

Answer 2

Answer:

The value of 9sec²A-9tan²A =9

Step-by-step explanation:

The value of 9sec²A-9tan²A

= 9(sec²A-tan²A)

/* By Trigonometric identity:

$\boxed {sec^{2}A-tan^{2}A=1}$ */

= 9 ×1

= 9

Therefore,.

The value of 9sec²A-9tan²A =9
