5. Equations of the form y’ = P(x)*y^2 + Q(x)*y + R(x) are called Riccati equations. i) If we know a solution y = φ(x) of this equation, then any other solution can be written in the form y(x) = φ(x)+ 1/v(x), where v(x) is an unknown function which satisfies a certain linear equation. Using the fact that φ and y both solve the above Riccati equation, find the differential equation that v satisfies. ii) Consider the equation 3y’ +...

f: R[x] to R is the map defined as f(p(x))=p(2) for any polynomial p(x) in R[x]. show that f is 1) a homomorphism 2) Ker(f)=(x-2)R[x] 3) prove that R[x]/Ker(f) is an isomorphism with R. (R in this case is the Reals so R[x]=a0+a1x+a1x^2...anx^n)
