Prove sin(x)/x=1

sin(x)/x does not always equal one. That would require that x=sin(x), assuming that x cannot be 0, which isn't always true. There are other trigonometric identities like cos^2(x)+sin^2(x) that do always equal 1, however.

That equation is false.

It doesn't....
Proof: sin(1)/1=0.84147...
If any x is false the equation is not always true

If your asking how to solve for x, go to wolfram alpha and enter in the equation, too lazy to solve it

But.... that's wrong...

sin(x)/x=1?

Then sin(30)/30=1, which isn't true... If I am making some sort of stupid mistake, someone point it out please, (politely, of course)
