Best Answer

by implicit differentiation you have

y+x*dy/dx-2dy/dx=0

solving for dy/dx you'll have

dy/dx=y/(2-x)

and solving for y in the original equation and plugging it back in, you'll get

dy/dx=1/(-x^2 +4x-4) which is your final answer

To find the derivative of the equation xy - 2y = 1, differentiate each term with respect to x using the product rule for the first term and the power rule for the second term. This yields dy/dx = (1 - 2x).

What is the antiderivative of e to the power of one divided by -x?

Powers of e are simple to integrate. The derivative of eu equals u'eu; inversely, the antiderivative of eu equals eu/u'. Therefore, the antiderivative of e1/-x equals (e1/-x)/{d/dx[1/-x]}. The derivative of 1/-x, which can also be expressed as x-1, equals (-1)x(-1-1) = -x-2 = -1/x2.
