How can I enter trigonometric values ​​in the "f" functions?

Wronskm ([sin (x), cos (x)])


thx

hi Fernando,
sorry for the delay in reply...
You can simply do so:
• type wronskm() or choose it from Vars/Programs
• wronskm([])
•wronskm([SIN(x), COS(x)])
using the functions SIN, COS in the key H and I, insert x via the key D in both, and separate them with the comma (key O).
You'll get a matrix:
\[
\begin{bmatrix}
SIN(x) & COS(x) \\
COS(x) & -SIN(x)
\end{bmatrix}
\]

Please, let me know if it helps.
