I have to find the 3 partial derrivatives of f(x,y,z) = x^2yz+3y-xcos(3yz)(adsbygoogle = window.adsbygoogle || []).push({});

I have solved for df/dx and df/dy and here are my solutions:

df/dx = 2xyz-cos3yz

df/dy = x^2z+3+3xzsin3yz

are these correct so i can continue with the problem?

Thanks for the help.
