Unformatted text preview: the domains of the derivatives? a) y = [ln(cos x )] e arcsin x b) y = ln r x + 1 x 1 ! c) y = x x 2 6. a) Using the identity sin(2 y ) = 2 sin y cos y , show that 2 arcsin x = arcsin(2 x p 1 x 2 ) . ( ) Hint: Let y = arcsin x . b) Plug in x = 1 into ( ). c) For what values of x is ( ) valid? Why?...
