What does sin^2(3x)+cos^2(3x) equal?

Question

Does it still equal 1 or does it equal 3 or what? can you even do it?

Answer 1

sin^2(3x)+cos^2(3x) = 1
----------
This is an identity. No matter what angle measure is, it is hold.

Answer 2

equals 1

Answer 3

It still equals 1.

Try an example.

If x=20 than 3x=60

cos^2(60) + sin^2(60) = 1

It doesn't matter if you call 60, 60 or 3(20)

Answer 4

It still equals 1. Sin² t + cos² t = 1 no matter what
t is.

Answer 5

i'm the boss of all my equines. we at the instant are not equivalent; there is by no skill a venture wherein they get to pick what we are able to do. If I say we are going for a experience, we are going for a experience. If I say i pick to hold that foot off the floor, that foot is arising. it is not a communicate, it is not an equivalent partnership wherein we weigh up the outcomes of a handful of recommendations: what I say is going. that doesn't propose i do no longer take care of my horses and ponies with admire. i've got faith we've a mutual admire and it could continually be a 2 way conversation in that I pay attention to what's being mentioned; i'm no longer dominant in a forceful way, in spite of if it somewhat is critical to a working courting and a clever, chuffed horse that i'm respected and observed because of the fact the boss. the final analysis is they don't seem to be human beings and we won't be able to have conversations approximately it. they're horses - working animals, no longer terrific pals - and correct training is considerable.

Answer 6

It is still one, punch it in your calculator of a couple different values of x and you'll see the answer is always 1
