On the first example problem for session 32 (http://ocw.mit.edu/courses/mathematics/1802scmultivariablecalculusfall2010/partbchainrulegradientanddirectionalderivatives/session32totaldifferentialsandthechainrule/MIT18_02SC_we_15_comb.pdf) why is the partial derivative of w with respect to x only 3x^2+y? Shouldn't the y and z coefficients remain for the 3x^2?

Best ResponseYou've already chosen the best response.0Definitely an error, not a typo. And the error is propagated throughout the rest of the solution, giving the wrong answer to the problem.

Best ResponseYou've already chosen the best response.0it is written 3x^2 yz + y so it is right the error is that dw/dy = x^3 z+ y while it has to be x^3 z+ x
