Question

sec⁴A - sec²A = how much​

Answer 1

Answer:

sec6B

Step-by-step explanation:

bec sec 4+2=6

A+A=B

Answer 2

Answer:

sec⁴A - sec²A

= sec²A(sec²A-1)

now we know, sec²θ - 1 = tan²θ

so we get:-

             sec²Atan²A

Now, this can also be made into :

(tan²A+1)tan²A         {because , sec²θ = tan²θ+1}

which is equal to :

               tan⁴A+tan²A
