# PetscDTPTrimmedSize
The size of the trimmed polynomial space of k-forms with a given degree and form degree, which can be evaluated in `PetscDTPTrimmedEvalJet()`. 
## Synopsis
```
#include "petscdt.h" 
PetscErrorCode PetscDTPTrimmedSize(PetscInt dim, PetscInt degree, PetscInt formDegree, PetscInt *size)
```

## Input Parameters

- ***dim -*** the number of variables in the multivariate polynomials
- ***degree -*** the degree (sum of degrees on the variables in a monomial) of the trimmed polynomial space.
- ***formDegree -*** the degree of the form



## Output Parameter

- ***size -*** The number ((`dim` + `degree`) choose (`dim` + `formDegree`)) x ((`degree` + `formDegree` - 1) choose (`formDegree`))
