Question

Find all solutions in the interval [0, 2π) sec2x - 2 = tan2x

Answer 1

Hint: 1 + tan^2 x = Sec^2 x

Answer 2

is it pi/4?

Answer 3

is that \(sec^{2} x\) or \(sec2x\)?

Answer 4

sec^2 x

Answer 5

in that case, use what Yahoo said and simplify...

Answer 6

is it pi/4?

Answer 7

wait a minute....is it tan^2 x too?

Answer 8

something's wrong with your question. you know why?
if you convert sec^2 x to 1+tan^2 x, the tan^2x on both sides will cancel giving
-1=0
which is absurd.
