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

0Integral of [1/(sin x cos x) dx] (substitute sin2 x + cos2 x for 1)= Integral of [(sin2 x + cos2 x)/(sin x cos x) dx]= Integral of [sin2 x/(sin x cos x) dx] + Integral of [cos2 x/(sin x cos x) dx]= Integral of (sin x/cos x dx) + Integral of (cos x/sin x dx)= Integral of tan x dx + Integral of cot x dx= ln |sec x| + ln |sin x| + C

To find the integral, you can split the integral of 3sinx-5cosx into two separate integrals. For the integral of 3sinx dx integral of sinx= -cosx you can pull the three out of the integral as a coefficient Therefore, integral of 3sinx dx= -3 cosx +C For the integral of -5cosx dx integral of cosx=sinx you can pull the -5 out of the integral as a coefficient Therefore the integral of -5cosxdx= -5sinx +C Therefore the integral of 3sinx-5cosx =-3cosx-5sinx + C

The integral of x cos(x) dx is cos(x) + x sin(x) + C

An indefinite integral is a version of an integral that, unlike a definite integral, returns an expression instead of a number. The general form of a definite integral is: ∫ba f(x) dx. The general form of an indefinite integral is: ∫ f(x) dx. An example of a definite integral is: ∫20 x2 dx. An example of an indefinite integral is: ∫ x2 dx In the definite case, the answer is 23/3 - 03/3 = 8/3. In the indefinite case, the answer is x3/3 + C, where C is an arbitrary constant.

By antiderivative do you mean integral? If yes, integral x^1 dx= (x^2)/2

Integral of 2x dx /(2x-2) Let 2x=u 2 dx = du dx = (1/2) du Integral of 2x dx /(2x-2) = Integral of (1/2) u du / (u-2) = Integral of 1/2 [ (u-2+2) / (u-2)] dx = Integral of 1/2 [ 1+ 2/(u-2)] dx = u/2 + (1/2) 2 ln(u-2) + C = u/2 + ln(u-2) + C = (2x/2) + ln(2x-2) + C = x + ln(2x-2) + C

integral x/(x-1) .dx = x - ln(x-1) + c where ln = natural logarithm and c = constant of integration alternatively if you meant: integral x/x - 1 .dx = c

The indefinite integral of (1/x^2)*dx is -1/x+C.

∫ -3x dx = -3/2 x2 + c

Yes, the integral of gx dx is g integral x dx. In this case, g is unrelated to x, so it can be treated as constant and pulled outside of the integration.

If you mean integral SQRT(4-x2)dx, 2arcsin(.5x)+.5xSQRT(4-x2).

If df(x)/dx = g(x), then integral [from a to b] g(x) dx = f(b)-f(a). In plain English: the definite integral can be calculated by finding the antiderivative, evaluating it at the endpoints, and subtracting.

âˆ« f(x) +g(x) dx = âˆ« f(x) dx + âˆ« g(x) dx.

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

See related link below for answer

Integral( sin(2x)dx) = -(cos(2x)/2) + C

The definite integral of the function f=x*exp(k*x) is (1/k)*(x-(1/k))*exp(k*x). So you have the answer to your questions by setting k equal to 1 then 2. I derived my formula by using integration by parts, setting u=x and dv=exp(k*x)dx.
