Question

9sec² A − 9tan² A is equal to
(a)1
(b)9
(c)8
(d)0

Answer 1

Answer:

The value of 9sec²A − 9tan² A is 9.

Among the given options option (b)  9  is correct.  

Step-by-step explanation:

Given : 9sec² A − 9tan² A

9sec² A − 9tan² A

= 9 (sec² A − tan²A)

= 9 ( sec² A− tan² A )

= 9 × 1  

[By using  an identity, sec² θ − tan² θ =  1]

9sec² A − 9tan² A =  9

Hence, the value of 9sec²A − 9tan² A is 9.
