0 for the lower limit 5 for the upper limit
t - mark as variable x = 2 nu = 1.5
Result = 0.179907
Estimated error = 1.4e-09
To verify this result, use the exact formula for the modified Bessel function of half-integer index. Input the following expression:
sqrt(PI/(2*x)) * exp(-x) * (1+1/x),
switch to the calculator mode and input the value of x:
x = 2
Then click the Start button.
You will obtain the same result:
Result = 0.179907
