Description
- On this page, you can expand, factor, and simplify polynomials.
- Variable names can be subscripted with underscores, such as
V_th. - Single-case, uppercase letters
C,E,N,O,QandSare not allowed in variable names. - Math function names such as
sin, atan, fft, fu, Matrix, etc. cannot be variable names. j,i,Iare all replaced byjand treated as imaginary units.- If you add subscripts to i and I, as in
I_D, V_i, they are not substituted forjand are not treated as imaginary units. - You can test how input characters are interpreted on the page "Evaluate Expressions".
Example
| Input | Evaluation | Description |
|---|---|---|
(x+1)*(x-1) |
$(x+1)(x-1)$ | * cannot be omitted. |
10**2 |
$10^2$ | ** is a power. |
j*j |
$-1$ | j is an imaginary unit. |
i*V |
$jV$ | i is replaced by j. |
(A+1)/2*B |
$\frac{(A+1)}{2} B$ | Different from below. |
(A+1)/(2*B) |
$\frac{(A+1)}{(2B)}$ | Different from above. |
V_1*I_bias |
$V_1 I_{bias}$ | Variables can be subscripted. |
