Question

Find the value of 9 secº A-9 tanº A
Pls help me

Answer 1

Answer:

I have solution for problem:9 sec°2A-9tan°2A

Step-by-step explanation:

We have, 9sec 2 A−9tan 2A

Let r=9sec 2A−9tan 2 A

r=9(sec 2A−tan 2 A)

We know that

sec 2 A−tan 2A=1

Therefore,

r=9×1=9

Hence, this is the answer.
