Question

What is `sin^2A/Cos^2A` equivalent to?

Answer 1

`tan^2A`, because `tanalpha = sinalpha/cosalpha`.

Hopefully this helps!

Answer 2

It is equivalent to a lot of things but the first thing people tend to see is `tan^2 A`

Explanation:

Well, I guess it depends on where you want to stop! You can find a lot of stuff that say the same thing in trigonometry or even in Math, in life in general!
`(sin^2A)/(cos^2A) = (1-cos^2A)/cos^2A= 1/cos^2A-cos^2A/cos^2A=sec^2A - 1= tan^2A`
I don't know in which form you've been asked to write your answer. Maybe, they just want you to say that it is equivalent to `tan^2 A`, which you can find from the very beginning.

Hope this helps :)
