POLYEVAL | Polynomial evaluation. Evaluates a polynomial with the | |
| specified coefficients for the value of x. |
|
| POLYEVAL([coefficients], value) |
|
| Example |
|
| For |
|
| ||
| 3432. |
|
POLYFORM | Polynomial form. Creates a polynomial in variable1 from | |
| expression. |
|
| POLYFORM(expression, variable1) |
|
| Example |
|
| POLYFORM((X+1)^2+1,X) returns X^2+2*X+2. | |
POLYROOT | Polynomial roots. Returns the roots for the | |
| polynomial with the specified n+1 coefficients. |
|
| POLYROOT([coefficients]) |
|
| Example |
|
| For |
|
| ||
|
| |
H I N T |
| |
The results of POLYROOT will often not be easily seen in | ||
| HOME due to the number of decimal places, especially if | |
| they are complex numbers. It is better to store the results | |
| of POLYROOT to a matrix. |
|
| For example, | M1 will |
| store the three complex cube roots of 8 to matrix M1 as | |
| a complex vector. Then you can see them easily by going | |
| to the Matrix Catalog. and access them individually in | |
| calculations by referring to M1(1), M1(2) etc. |
