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!

0{xe^x dx integrate by parts let f(x) = x so f'(x) = 1 and g(x) = e^x so g'(x) = e^x so.. f(x)*g(x) - {(g(x)*f'(x)) dx therefore xe^x - {(e^x * 1) dx so.. xe^x - e^x + C factorize so... (x-1)e^x + C

integrate(x5x dx) simplifies to integrate(5x^2 dx), and using the power rule of integration, add one to the power of x and divide the term by that number. Thus, x5x dx integrated is (5/3)x^3

integrate of x is 1/2x^2. integrate of 1 is x

x-1 = 1/x ∫1/x dx = ln x + C

If x has the power 2 then you want the integral of x2, I think. When you integrate this you get : x3/3 , plus a constant.

I can't integrate a-x /x-3 ?

let u = x du=dx let dv= e^x v=e^x ∫ xe^(x)dx = xe^x - ∫ e^(x)dx = xe^x - e^x = e^x ( x-1 ) + c

Do it by parts. Int(u.dv) = u.v - int(v.du) Let x = u, then dx = du. Let e^x = dv, then v = e^x. Plug into formula: xe^x - int(e^x.dx) = x.e^x - e^x or e^x(x-1)+C

xe^(5x) is an expression involving x and Euler's constant

root x=x^(1/2) and 4x =4 x^1 you add the exponents then integrate as usual. The answer you should get is 4.

Apparently that can't be solved with a finite number of so-called "elementary functions". You can get the beginning of the series expansion here: http://www.wolframalpha.com/input/?i=integrate+x^x

To integrate a function you find what the function you have is the derivative of. for example the derivative of x^2 is 2x. so the integral of 2x is x^2.

Integrate 2sin(x)cos(x)dxLet u = cos(x) and du = -sin(x)dx and pull out the -2:-2[Integral(u*du)]Integrate with respect to u:-2(u2)/2 + CSimplify:-u2 + CReplace u with cos(x):-cos2(x) + C

No chemical element with the chemical symbol X. Xenon has the symbol Xe.

The integral of cot(x)dx is ln|sin(x)| + C

Xe is Xenon, an atom.Xe is Xenon, an atom.Xe is Xenon, an atom.Xe is Xenon, an atom.

There is no element that starts with the letter "X" but there is an "Xe" which is Xenon.Xenotime

The integral of esec(x) dx is not a function that may be expressed in terms of well-studied mathematical functions, elementary or nonelementary. In general, it must be evaluated by numerical methods.

1/2(x-ln(sin(x)+cos(x)))

x/sqrt(x)=sqrt(x) integral sqrt(x)=2/3x3/2

Let us say that f(x)=x^4A derivative is the opposite to an integral.If you were to integrate x^4, the first process is taking the power [which in this case is 4], multiplying it by any value before the x [which is 1], then subtracting 1 from the initial power [4]. This leaves 4x^3. The final step is taking the integral of what is 'inside' the power [which is (x)], and multiplying this to the entire answer, which results in 4x^3 x 1 = 4x^3If you were to derive (x)^4, you would just add 1 to the power [4] to become (x)^5 then put the value of the power as the denominator and the function as a numerator. This leaves [(x^5)/(5)]To assure that the derivative is correct, integrate it. (x^5) would become 5x^4. Since (x^5) is over (5), [(5x^4)/(5)] cancels the 5 on the numerator and denominator, thus leaving the original function of x^4

multiply the number times x. For example, the integral of 3 is 3x.
