Question #ca0cb Calculus Applications of Definite Integrals Solving Separable Differential Equations 1 Answer Roy E. Dec 4, 2016 If #f(x,y,z) = x sin(y+2z) + xy^2#, #(delf)/(delx)|_{y,z}=sin(y+2z)+y^2# Explanation: Assuming that the function is of three variable #x,y,z# then to partially differentiate wrt one of the three just treat the other two as constants.
