Question about trig

Answer 1

\[\large \sin^n(x)+\cos^n(x)=1\] if n is even, is this always true?

Answer 2

Hmm I don't think it's true for any n except n=2, is it? :O
Thinking...

Answer 3

And n > 0

Answer 4

it is true for 0<n<=2.....
for n>2 sin^n+cos^n <1

Answer 5

i guess so...get confirmed

Answer 6

And n>0 ... ? what?
There are no even numbers been 0 and 2.

I don't understand what you're saying.

Answer 7

no I just meant any even number that was greater than 0. So I guess it isn't true then!

Answer 8

Ya I don't so :)
Cool question though.
