How do you integrate xe power x?
Use integration by parts. integral of xe^xdx =xe^x-integral of e^xdx. This is xe^x-e^x +C. Check by differentiating. We get x(e^x)+e^x(1)-e^x, which equals xe^x. That's it!
What is the integral of sin squared x times cos squared x?
∫sin²x cos²x dx = ∫(1-cos²x)cos²x dx =∫cos²xdx-⌠cos²xcos²xdx =1/2⌠1+cos2x dx-1/2⌠[(1+cos2x)(1+cos2x)] Do the operations, distributions, arrange common numbers, and try to sort out the factors as a polynomiom. Then, =1/2x+1/4sin2x-1/2x-1/2sin2x-1/4x-1/16sin4x =-1/4x-1/16sin4x
Integral of xlnxdx?
integration by parts. Let u=lnx, dv=xdx-->du=(1/x)dx, v=.5x^2. Integral of (xlnxdx)=lnx*.5x^2-integral of .5x^2(1/x)dx=lnx*.5x^2-integral of .5xdx=lnx*.5x^2-(1/6)x^3. That's it.

Does factorial only work for whole numbers?
No! Though this depends on definition. Usually we define n! = n(n-1)....3.2.1, which is only sensible when n is a whole number. However, we can also define n! = int(0, infinity, xne-x, x) (the integral of xne-xdx from 0 to infinity) This actually gives us all the same results as the usual definition, but also allows us to calculate for non-integer values of n. For example 1.5! = 1.3293... 6.7! = 2769.83036... -0.8! = 4.5908... 0! = 1 Interestingly with this definition, all negative whole numbers have an undefined (infinite) factorial value.
Integrate of x lnx?
You need to use integration by parts so that (cap. S stands for ingegral) Su*dv = uv - Sv*du So for Sxln(x) you need to choose your u and dv, then use those to solve for du and v. ln(x) is not easy to integrate, but it is easy to differentiate, so choose it as your "u", therefore xdx would be "dv" u = ln(x); dv = xdx du = (1/x)dx; v = 1/2*x^2 So now you just plug it into the formula above Sudv = uv - Svdu = ln(x)*(x^2/2) - S(x^2/2)*(dx/x) --- pull out the 1/2, and simplify x^2/x = ln(x)*(x^2/2) - 1/2*[Sxdx] = 1/2*(x^2ln(x)) - 1/2*[1/2*x^2] = 1/2*(x^2ln(x)) - 1/4(x^2) + C
Can you play halo 3 on an Xbox instead of an Xbox 360?
To get the point across, it is no. The Xbox and Xbox 360 have different types of loading formats. Xbox reads .ini files, and Xbox 360 reads .xdx and .ini(reverse compatibility) files. Also, graphics are rendered better on the Xbox 360 and accelerates its hardware due to 2D and 3D games, especially Halo 3's 3D graphics(rocks, people, vehicles, and even SPAWN PADS are 3D). The game saves would be bad, meaning that the necessary drive(External/Internal HDD on Xbox 360) would not be available, canceling game saving and continuing with empty progress - like the NES.
What is Massachusetts Institute of Technology?
MIT is a collage in Massachusetts that is not private but is mostly for technology. Its mascot is named Tim and is a beaver. Some people think that MIT's sport is football but MIT's sport is Hockey. MIT is also called the Engineers. Even though Hockey is MIT's sport, they still play at other sports to. For example, MIT also has a Football team but Tim the beaver does not always show up. MIT's normal cheer goes like this "I am a beaver, your a beaver, and we are beavers all, and when we get together we do the beaver call to the U to the UDX E to the XDX, cosine tangent side 3.14159, identical, radical MUDV slapstick slide-roll MIT, GO TECH!
