f(x,y) = x√(1+y^2)
fx = (√1+y^2)
fy = xy/(√1+y^2)
Just treat the other variables as constants.
a)find the first partial derivatives of f(x y)= x √1+y^2
b)find the first partial derivatives of f(x,y)= e^x ln y at the point (0,e)

fx=e^xlny
fy=e^x/y
fx=e^(0)ln(e)=1
fy=1/e
fy=e^x/y
fx=e^(0)ln(e)=1
fy=1/e
