Hi guys, I think the question is clear (lol) How can the Sin(x)/(x) function be integrated? i heared it can be integrated using a series, anyone can explain? Last added : I remembered the function e^(x^2) how also can it be integrated? Thanks, TheDestroyer Last edited: Feb 24, 2005.

Suppose now we wish to ﬁnd the integral Z cos(3x+4)dx (2) Observe that if we make a substitution u = 3x + 4, the integrand will then contain the much simpler form cosu which we will be able to integrate. As before, du = du dx dx and so with u = 3x+4 and du dx = 3 It follows that du = du dx dx = 3dx So, substituting u for 3x+4, and with dx = 1 3 du in Equation (2) we have Z cos(3x+4)dx = Z 1...

So I'll put the cosine of x right over here, and then the negative, we can take it out of the integral sign. And so we're subtracting a negative. That becomes a positive. And of course, we have our dx right over there. And you might say, Sal, we're not making any progress. This thing right over here, we now expressed in terms of an integral that was our original integral. We've come back full how to take correct bra size Integral of cos^2x=(1/2)(cosxsinx+x)+C Here is why: Here is one method: use integration by parts and let u=cosx and dv=cosxdx du=-sinx v=sinx.

But if we set g prime of x equaling to x and then we had to take its antiderivative, we get x squared over 2, that is more complicated. So let me make it clear over here. We are assigning f of x to be equal to x. And that means that the derivative of f is going to be equal to 1. We are assigning-- I'll write it right here-- g prime of x to be equal to cosine of x, which means g of x is equal how to take a picture of a website 2007-09-07 · Evaluate the integral from 0 to pi/2 of cos^3 (x)dx I got to the end and my answer was negative.
