Question

Trig Identities

Answer 1

\[\cot^2x - \tan^2x =1\]

Answer 2

true or false?

Answer 3

According to the Pythagorean Identities, \[\tan^2 x + 1 = \sec^2 x\].

Answer 4

If you move \[\tan^2 x \] to the other side. . . you get : \[\tan^2 x + 1 = \cot^2 x.\]

Answer 5

I think false, because \[\cot^2x-\tan^2x=1\] turns into \[\cot^2x=\sec^2x\] through Pythagorean identities

Answer 6

^ Yeah.
