WebWhen we write dx = dx dudu, d x = d x d u d u, the number dx du d x d u is called the Jacobian of x x with respect to u. u. The Jacobian tells us how lengths are altered when we change coordinate systems. We now generalize this to polar coordinates. Before we're done with this section, we'll generalize the Jacobian to any change of coordinates. dancy dreamWebExcept for the case of constant solutions, it is usually not possible to find explicit expression for thesolutions of a nonlinear autonomous system, However, if the system contains such an expression as x^2+y^2we can solve some nonlinear systems by changing to polar coordinates.(a) Let x =r cos θ and y = r sin θ where r and θ are functions of t. birmingham alabama church of christ
