Extracted text: Consider the following Differential Equation (Riccati Equation): y' = p(x) + q(x)y+r(x)y² If u is a solution of the given DE, use the transformation: 1 y = u +- v Prove that the solution of the DE: d k dx 1 + (y')², is a circle equation considering that k is a constant. Then, find the center and radius of this circle given that y(-1) = y(1) = 0
