Exact Equation | Britannica
exact equation, type of differential equation that can be solved directly without the use of any of the special techniques in the subject. A first-order differential equation (of one variable) is called exact, or an exact differential, if it is the result of a simple differentiation. The equation P(x, y)y′ + Q(x, y) = 0, or in the equivalent alternate notation P(x, y)dy + Q(x, y)dx = 0, is exact if Px(x, y) = Qy(x, y). (The subscripts in this equation indicate which variable the partial derivative is taken with respect to.) In this case, there will be a function exact equation, type of differential equation that can be solved directly without the use of any of the special techniques in the subject. [ReadMore..]

Non-exact 1st Order Differential Equation? Kindly Solve This Non ...
y = arcsin(e^(C-x)/x^2) We have: (x+2)siny \ dx + xcosy \ dy = 0 Which we can write in standard form as: xcosy \ dy/dx + (x+2)siny = 0 We note that we do not require the use of an Integrating Factor as this is a separable First Order differential equation, thus we can collect terms and separate the variables to get \ \ \ \ \ cosy/siny \ dy/dx + (x+2)/x = 0 :. int \ coty \ dy = - int \ (x+2)/x \ dx And we integrate to get: ln siny = -x - 2lnx + C Exponentiating we get: siny = e^(-x - 2lnx + C) \ \ \ \ \ \ \ = e^(C-x)e^(- 2lnx) \ \ \ \ \ \ \ = e^(C-x)e^(ln(1/x^2)) \ \ \ \ \ \ \ = e^(C-x)(1/x^2) \ \ \ \ \ \ \ = e^(C-x)/x^2 And finally: y = arcsin(e^(C-x)/x^2) Jan 8, 2018 ... y=arcsin(eC−xx2). Explanation: We have: (x+2)siny dx+xcosy dy=0. Which we can write in standard form as: xcosy dydx+(x+2)siny=0. [ReadMore..]
