# CASA Function: adjointCurve

Computes an adjoint curve to a given curve.

### Calling Sequence:

- C := adjointCurve(A,deg,c)

### Parameters:

- A : algset
- An algebraic set defining a plane curve.

- deg : posint
- Degree of the adjoint curve

- w : name
- An unevaluated name to be used to construct names for parameters.

### Result:

- C : polynom
- A linear system of plane curves.

### Description:

- The function computes a linear system C of plane curves passing through all singularities (including the neighboring ones) of a given plane curve A with multiplicities m_P(c) >= m_P(A) - 1 for all c in C and all points P of the space. The argument holds upon return the coefficients of the adjoint curve.

### Examples:

`> ` **a:=mkImplAlgSet([y^2*z^3-x^5],[x,y,z],["basespace"="projective"]);**

`> ` **adjointCurve(a,3,w);**
