If (x 2y)dy/dx=2x-y what is the value of.
Radda [10]

The second differential of the function is 3/7

Given the differential function (x +2y)=\frac{dy}{dx} (2x-y)

Differentiate both sides with respect to x implicitly

(x +2y)=\frac{dy}{dx} (2x-y)

1+2y'=y"(2x-y)+y'(2-y')  \\y''=\frac{1+2y'}{(2x-y)+y'(2-y') }

Get the first derivative at the point (3, 0)

y'=\frac{2x-y}{x+2y} \\y'=\frac{2(3)-0}{0+2(3)}\\y'=\frac{6}{6} \\y'=1

Substitute into the second derivative to have:

y''=\frac{1+2y'}{(2x-y)+y'(2-y') }\\y''=\frac{1+2(1)}{(2(3)-0)+(1)(2-(1)) }\\y''=\frac{3}{6+1} \\y''=\frac{3}{7}

Hence the second differential of the function is 3/7
