The given differential equation is, (1 y 2) dx = (tan 1 y x) dy ⇒ d x d y = 1 1 y 2 ( tan − 1 y − x) ⇒ d x d y x 1 y 2 = tan − 1 y 1 y 2 Now, it is in the standard form of a firstorder linear differential equation Here, P = 1 1 y 2, Q = tan − 1 y 1 y 2Dy dx = f0(x) However, we can treat dy/dx as a fraction and factor out the dx dy = f0(x)dx where dy and dx are called differentialsIfdy/dx can be interpreted as "the slope of a function", then dy is the "rise" and dx is the "run" Another way of looking at it is as follows • dy = the change in y • dx = the change in x Stepbystep explanation Taking log on both sides, Differentiating with respect to x, we have Again differentiating with respect to x, Now, the given equation is = = arrenhasyd and 57 more users found this answer helpful heart outlined
