Look for the function pdsolve
, which finds the solutions for PDEs and systems of PDEs. See help("pdsolve") for more info.
Sorry, but I could not fully understand your notation (looks weird on my system), but you can define a function of two variables as follows. Note that you differentiate with the diff
function, that the exponential function is written expO
, the logarithm ln()
, and multiplication is denoted by *
> z := proc (x, y) options operator, arrow; exp(y)*ln(x*y) end proc;
z := (x, y) -> exp(y) ln(x y)
> diff(z(x, y), x);
> diff(z(x, y), x, x)
You can also use the palettes located on the LHS of the screen to enter your expressions.
