(Exact solution of ˙x = sinx) As shown in the text, ˙x = sinx has the solution t = ln|(cscx0 + cotx0)/(cscx + cotx)|, where x0 = x(0) is the initial value of x. Oct 30, 2020 ... I am expanding on my comment. You want to find x,y such that: XcotX+YcotY=0, X=d×x, Y=d×y,andY=f(X). d can be seen as a scaling parameter, ...
