	Inverse Trig Functions
	Here is a true or false problem: (arcsin x)**2 + (arccos x)**2 = 1 I know that this is false and can prove it via a specific example, say with x = 0.5 However I seem to be unable to come up with a generalized expression for the left hand side of the equation that would also show that it is false.

	Galois theory question
	Can anyone please explain why the following statement is true? Unfortunately the text omitted a proof. If K and L are fields where L is a finite extension of K, then there exists a polynomial f(x) in K[x] so that L is contained in the splitting field of f(x) over K. Many thanks.

Not isomorphic, quadratic fields

Hello, I would like to show that Q(sqrt(2)) is not isomorphic to Q(sqrt(3))--well, at least I believe this to be the case. Here Q(sqrt(2)) = {a + b*sqrt(2) : a,b rational} and similarly for Q(sqrt(3)). I've tried playing about to deduce a contradiction but nothing seems to work really. Any ideas? I'm sure it is relatively simple but it's not clicking.... más » Por Solomon Welsh  - 14 nov - 6 nuevo(s) de 6 mensajes
