Question: Unable to find parameter at x=0 y=0 of a function.

Hey there,


I'm trying to evaluate some parameter of a function when x and y are 0.


Here's the code:

> Y1 := proc (x) options operator, arrow; int(`Y1"`(x), x)+C1 end proc;


> solve({Y1(0) = 0}, {C1});

But unfortunately I get the following error:

Error, (in int) integration range or variable must be specified in the second argument, got 0


I know that the value of C1 is gonna be 0, but I want the program to say me this...


Please, some help.

Please Wait...
