I have a Polynomial of two variables f(x,y) . I want to find the maximum of the function for a fixed value of y that depends on y and x changes on a closed interval. basically i want to find Max(f(x,b) : b is a constant and 0<x&lt;1 ).="" is="" there="" any="" way="" to="" do="" that="" in="" sage="" and="" the="" result="" be="" a="" function="" in="" y.<="" p="">
