pi -- 4 / | | sin(4*x) | -------- dx | x | / 0
Integral(sin(4*x)/x, (x, 0, pi/4))
SiRule(a=4, b=0, context=sin(4*x)/x, symbol=x)
Add the constant of integration:
The answer is:
/ | | sin(4*x) | -------- dx = C + Si(4*x) | x | /
Si(pi)
=
Si(pi)
Si(pi)
Use the examples entering the upper and lower limits of integration.
