Find the partial derivative y with respect to s for the following function:
y=[((x1)^2)+(x1)(x2)+((x2)^2)]/((x1)+(x2))
where x1=s+2 and x2=s^2+t^2+t .
x1 means x subscript 1
x2 means x subscript 2
y=[((x1)^2)+(x1)(x2)+((x2)^2)]/((x1)+(x2))
where x1=s+2 and x2=s^2+t^2+t .
x1 means x subscript 1
x2 means x subscript 2
