Find par(z)/par(t) at s=1, t=0
when z= ln(x+y), x=s+t, y=s-t
Not sure how to approach cause if i plug in s's and t's i get an answer of 0 because taking the partial with respect to t yields a zero. Can someone shed some light on how to correctly solve?
par(z)/par(t) = partial derivative of z with respect to t
