In: Math
f(x) = (x^1/2)/lnx
#16: What is the indefinite integral of f(x)?
Compute: S f(x) dx.
#17: What is the definite integral of f(x) from lower limit x = 4 to upper limit x = 9?
Compute: S 4,9 f(x) dx
Using method of substitution
then ,
let 3t = u, then 3dt = du,
This can not be integrated to any elementary function.
It can be written as series using by parts infinite times:
Definite integral :
as this is infinite series, the given sum is an approximation (using calculator).
