Partial Derivatives. For each of the following multi-variable functions, compute the
partial derivatives with respect to both x and y.
a. ,f(x,y)=xy
b. f(x,y)=2x+3y
c. f(x,y)=x^(2)y^(4)
d. f(x,y)=lnx+2lny
e. f(x,y)=2\sqrt(x)+2\sqrt(y)
f. f(x,y)=(x)/(y)
g. f(x,y)=(y)/(x)
please do this in paper and attach a image file as i cant understand when its keyboard written.
