I am confuse. Please help.
Given w=sin xy + y ln xz + z, x=et and y =t2. Use the method of partial differentiation to find dw/dt.
* Please show me the right solution for this so that i can compare it to my work. i am doubtful for my solution.
If f(x,y,z)=xyz +x2 + ln(y/z), prove that fxyzx = fzxxy.
