Suppose

`z=x^(2)sin(y),x=s^(2)-2t^(2),y=8st`

. A. Use the chain rule to find

`(delz)/(dels)`

and

`(delz)/(delt)`

as functions of

`x,y,s`

and

`t`

.

```
(delz)/(dels)=
(delz)/(delt)=
```

B. Find the numerical values of

`(delz)/(dels)`

and

`(delz)/(delt)`

when

```
(s,t)=(-4,-3)
(delz)/(dels)(-4,-3)=
(delz)/(delt)(-4,-3)=
```
