Math(Please check. Thank You)
1) solve:e^x(x^2-4)=0 e^x=0 and then (x+2)(x-2) so x=2, -2 2) differentiate: y=ln(6x^2 - 3x + 1) 1/(6x^2 - 3x + 1) * 12x-3 3) differentiate: y=e^-3x+2 -3 * e^-3x+2 4) evaluate: 2^4-x=8 2^4-x = 2^3 4-x = 3 -x=-1 so x=1 5) differentiate: x^3 + y^3 -6 =0 3x^2 + 3y^2 6) A ...

Can someone please differentiate y = sin x / x for me? What I did was put (sin x)(x)^-1 and used the product rule... So for me it was (sin x)[-1(x)^-2] + [(x)^-1(cos x)] Now as I'm looking at a similar homework problem I think my method may be wrong... If my method is wrong it...
