I'm siiting here working on this math assignment, and I'm having big
problems figuring out
the integrals of three different functions. If anyone out there would be so
kind that they would
help me with the methods and the answers, I would be eternally thankful...

The integral of: x times the square root of x^2+1 dx

The integral of: sin^2(t)*cos(t) dt

The integral of: 4*ln(x)/x dx


Thanx alot...
