Verify the following equation is an identity. \frac{(\sin^4(x) - \cos^4(x))}{(\sin^3(x) - \cos^3(x))} = \frac{(\sin(x) + \cos(x))}{(1 + \sin(x) \cos(x))} Simplify and write the trig...
Does the identity cos2(x)+sin2(x)=1 hold in a unital Banach algebra where 1 is the unit? https://math.stackexchange.com/q/2487526 The Riesz functional calculus map f↦f(x) is an algebra homomorphism. So for any element x in a unital Banach algebra and f,g analytic functions on ...
