WebTranscript. One useful property of indefinite integrals is the constant multiple rule. This rule means that you can pull constants out of the integral, which can simplify the problem. For example, the integral of 2x + 4 is the same as the 2 multiplied by the integral of x + 2. However, it is important that only constants—not variables—are ... WebAnswer (1 of 3): You most certainly can. Just look; I'll do it now: 2 \int (-\sin x) dx \int \cos x dx = 2 \cos x \sin x = \sin 2x.

WebNov 16, 2024 · Chapter 15 : Multiple Integrals. In Calculus I we moved on to the subject of integrals once we had finished the discussion of derivatives. The same is true in this course. Now that we have finished our discussion of derivatives of functions of more than one variable we need to move on to integrals of functions of two or three variables. WebOK, we have x multiplied by cos (x), so integration by parts is a good choice.
