Question

5 sec^2 A - 5 tan^2 A + 1 =​

Answer 1

Answer:

hello

Step-by-step explanation:

the answer is

This question can be easily solved by using the identity = sec^A - tan^2A => 1

According to the question = 5tan^2A - 5sec^2A

=>>> 5tan^2 A - 5sec ^2 A= -5 .

Answer = - 5

Hope It Helps You ^_^

Answer 2

Answer:

-4

Step-by-step explanations:

5(tan^2A- sec^2)

-5+1=-4 {sec^2A-tan^2A=1}
