In this video we will solve another non exact differential equations of type 4 by checking the exactness and then finding a suitable integrating factorSo si So setting the expression 2 x d x 2 y d y equal to 0 is the condition under which a tiny step stays on the circle What I don't understand is this is the solution my textbook gave me x 2 y 2 = 25 d d x ( x 2 y 2) = d d x 25 Remembering that y is a function of x and using the chain rule, we have d d x ( y 2) = d d x ( y 2) d y d x = 2 y d y d x You can insert dy/dx = 1 at this point x^2*2ydy/dx 2x*y^2 x*dy/dx y =0 You then get an equation relating x and y You also know that x and y are on te curve, so they satisfy the equation of the curve x^2y^2xy = 2 So, you have two equations for the two unknowns x and y 👍 👎
