I want to find the definite integral of(adsbygoogle = window.adsbygoogle || []).push({});

arccos(sqrt(1+x)/10)/(sqrt(x)*x^(2/3))

,over [0,pi/2].

I ran the following code in Matlab,

"syms w

double(vpa(int(acos((w + 1)^(1/2)/10)/(w^(1/2)*(w + 1)^(3/2)),w,0,pi/2)))"

and got this error message,

"??? Error using ==> mupadmex

Error in MuPAD command: DOUBLE cannot convert the input expression into a

double array.

If the input expression contains a symbolic variable, use the VPA function

instead.

Error in ==> sym.sym>sym.double at 936

Xstr = mupadmex('symobj::double', S.s, 0);

Error in ==> HW at 4

double(vpa(int(acos((w + 1)^(1/2)/10)/(w^(1/2)*(w + 1)^(3/2)),w,0,pi/2)))".

Anybody has met such situation like me before? I appreciate any comment!
