I tried multiplying by ϕ ( x) (a function depending only on x in order to find the integrating factor) but the EDO involving the integrating factor was not ordinary. I then tried with ϕ ( y) and I almost got it: Websin(x+y)sin(x−y) = 21[cos2y− cos2x] Explanation: We can use the product to sum formula sinAsinB = 21[cos(A− B)− cos(A+B)] ... First of all let's write sin(x− y) = sin(x)cos(y)−cos(x)sin(y) In order to have a better writing for the function: g(x,y) = sin(x)(1+ cos(y))+sin(y)(1−cos(x)) Now this is a ... y′ + sin(x +y) = sin(x− y ...

How can I solve $y-xy

WebSince $y'' + sin(x)y = 0$ is already in standard form, we can see that $x=0$ is an ordinary point. The sine is analytic at $x=0$ so we don't have any singular points to worry about. The next step is to use a Maclaurin series expansion for $\sin(x)$ . WebJul 28, 2016 · For the right side, however, you must make use of the chain rule for derivatives of composite functions (functions of functions). Thus. d dx (sin(x + y)) = cos(x + y) × d dx (x + y) = cos(x + y)(1 + dy dx) Thus, we get. dy dx = cos(x + y)(1 + dy dx) We can easily solve this for the quantity dy dx: (1 −(cos(x +y)) dy dx = cos(x +y) ⇒ dy dx ... siebel loyalty 08
