Find the derivative of <br> |x|/(x-1)
ki77a [65]
\bf \cfrac{|x|}{x-1}\iff \cfrac{\sqrt{x^2}}{x-1}\iff \cfrac{(x^2)^{\frac{1}{2}}}{x-1}&#10;\\\\\\&#10;\textit{using the quotient rule}&#10;\\\\\\&#10;\cfrac{dy}{dx}=\cfrac{\frac{1}{2}(x^2)^{-\frac{1}{2}}\cdot 2x(x-1)-(x^2)^{\frac{1}{2}}\cdot 1}{(x-1)^2}

\bf \cfrac{dy}{dx}=\cfrac{\frac{x(x-1)-(x^2)^{\frac{1}{2}}}{(x^2)^{\frac{1}{2}}}}{(x-1)^2}\implies \cfrac{dy}{dx}=\cfrac{x(x-1)-(x^2)^{\frac{1}{2}}}{(x^2)^{\frac{1}{2}}(x-1)^2}&#10;\\\\\\\cfrac{dy}{dx}=\cfrac{x(x-1)-|x|}{|x|(x-1)^2}

Find the equation of the tangent line to the curve y=6sinx at the point (π/6,3
Aloiza [94]
Hello:
f(x) =6sin(x)
f'(x) = 6 cos(x)

the equation of the tangent line is : y=f'(π/6)(x-π/6)+f(<span>π/6)
f'(</span>π/6)=6cos(π/6)=6×(√3/2)=3<span>√3
f(</span>π/6) =3
the equation is :  y = 3√3(x-π/6)+3
