Calculus and Vector
Please can answer the questions on the attachment

There is a minus typo in the problem. Either the field is =xy^2 i  x^2 yj + 2(x^2+y^2)k or the field is =xy^2 i + x^2 yj + 2(x^2+y^2)k

There was no typo, sorry. The correct field has a z at the end but it looked like a 2 to me: xy^2 i  x^2 yj + z(x^2+y^2)k The field must be =xy^2 ix^2 yj+2z(x^2+y^2)k

* The field must be =xy^2 i  x^2 yj + z(x^2+y^2)k
