A curve has the equation x^2+2y^2=3x, by differentiating implicitly find dy/dy in terms of x and y.

We shall differentiate each term in the equation with respect to x. dy/dx (x 2 ) = 2x dy/dx (2y 2 ) = 4y dy/dx dy/dx (3x) = 3 So we now have the equation 2x + 4y dy/dx =3 We now have to rearrange to get in t...
