Calculate $\partial(|z|^2+1)$ and $\bar{\partial}((\bar{z}|z|^2+1) \cdot \sin(z))$

I don't understand this notation.

Calculate $\partial(|z|^2+1)$ and $\bar{\partial}((\bar{z}|z|^2+1)\cdot \sin(z))$

They're asking me to find the derivatives with respect to $z$ and $\bar{z}$ resp.?

In that case, are my solutions correct?

$a)$ $\partial(|z|^2+1)=\partial(\bar{z}z+1)=\bar{z}$

$b)$ $\bar{\partial}((\bar{z}|z|^2+1)\cdot \sin(z))=\bar{\partial}((\bar{z}^2\cdot z+1)\cdot \sin(z))=2\bar{z}z\cdot \sin(z)$

Thanks for your time.
