Subject: problems integrating a function
Could any of you find the numerical solution to the integral of sin[(x-pi)/sqrt(x)] from pi/100 to pi?
S = int(sin((x-pi)/sqrt(x)),x=pi/100..pi)
You may copy and paste there.
I have already tried both Matlab and Scilab.
From Matlab I get:
Warning: Explicit integral could not be found.
> In sym.int at 64
In char.int at 9
int(-sin(1/x^(1/2)*(pi - x)), x = pi/100..pi)
From scilab (I installed scilab just to integrate this function):
at line 70 of function integrate called by :
The solution is -1.295820
I just can't get Matlab to find it.
