Question

secA +tanA =m, than sec^4A-tan^4A-2secA*tanA =?​

Answer 1

SK over to help you to the money bill of sale in the money bill for this position is 3 4 A of a number less than the

Answer 2

Answer:m^2

Explanation:=(sec^2 a + tan^2 a)(sec^2 a - tan^2 a) - 2sec a tan a

=sec^2 a + tan^2 a - 2sec a tan a

=(sec a - tan a)^2

now,

We know that,

sec^2 a - tan^2 a = 1

=(sec a - tan a) (sec a + tan a)=1

=(sec a - tan a) (m) = 1

=(sec a - tan a)=1/m

on square both sides,

=(sec a - tan a)^2 = 1/m^2
