@Eyad We have to find the equation of the tangent to the curve $$y=x^2+x^3$$ at the point (1, 0) First find $$\frac{dy}{dx}$$ at the point (1, 0) this will be the slope of the tangent at (1, 0) and then you can find the equation using this $\frac{(y-y1)}{(x-x1)}=m$ where $(x1,y1)=(1, 0)$ and $\large m= ( \frac{dy}{dx})_{(1,0)}$ Can you try now?

so its gonna be $\frac{y-0}{x-1}=0$ ?

@ash2326 .

$\frac{dy}{dx}=3x^2+2x$ put x=1 and y=0 $\frac{dy}{dx}=3+2=5$

Oh Sry i think i need some sleep xD, U did great :D Although its $2x-3x^2 ...$ where the slope is -1 TY ^_^

You really are sleepy:P you wrote y=x^2+x^3 instead of y=x^2-x^3

OH LOL ,Its y=x^2-x^3 .. Night :D
