# 3d plot syntax issue

I try this in Sage 5.11 Notebook:

```
var (x' y')
plot3d(x^2 y^2,(x,-2,2),(y-3,3))
```

But I got syntax error. I typed the figures correctly, but I don't know how to solve the syntax error.

The issue is with `x^2 y^2`

. You need to tell sage the operation between $x^2$ and $y^2$. Is your function $x^2\cdot y^2$? If so, you need:

```
plot3d(x^2*y^2,(x,-2,2),(y,-2,2)).
```

As a note, it *is*possible to use this syntax with implicit multiplication - see e.g. http://math.stackexchange.com/a/11866...
