Compute the integral \$$\\int {x{2^x}dx}.\$$ Solution. Keeping in mind the ILATE rule, we can choose \${u = x,\\;\\;}\\kern0pt{dv = {2^x}dx.}\$ Then 1−3cos2x+3cos2 2x− cos3 2xdx. Now we have four integrals to evaluate: Z 1dx = x and Z −3cos2xdx = − 3 2 sin2x 170 Chapter 8 Techniques of Integration are easy. The cos3 2x integral is like the previous example: Z −cos3 2xdx = −cos2xcos2 2xdx = Z −cos2x(1−sin2 2x)dx = Z − 1 2 (1− u2)du = − 1 2 u− u = − . 4 .

Further suppose that Z x 0 f(t)dt = Z 1 x f(t)dt for any x ∈ [0,1]. Show that f(x) = 0 for any x ∈ [0,1]. 3 Note that in the second integral on the right hand side, sin 1 xis the antiderivative of R p1 1 x2 dx. In the rst integral on the right hand side make the u-substitution: " u= 1 x2 du= 2xdx Then Z 3x p 1 x2 dx= 3 2 1 p u du= 3 2 2 p u= 3 p 1 x2: Thus the given integral is 3 p 1 x2 + 2sin 1 x+ C. 2 Now let’s consider a deﬁnite integral, I ≡ R1 0 √ 3x+4dx. Method 1: By our previous result for the indeﬁnite integral, I = 2 9 (3x+4)3/2 1 0 = 2 9 × 73/2 − 2 9 ×43/2. Method 2: Suppose we had not already found the antiderivative.

Textbook Authors: Thomas Jr., George B. , ISBN-10: 0-32187-896-5, ISBN-13: 978-0-32187-896-0, Publisher: Pearson I assume that by $(2xy+y)dx+(x^2-x)dy$, you mean $\int (2xy+y)dx+\int (x^2-x)dy$. To solve this equation, it should be considered a single variable integral: $\int (ax)dx$, for instance (where “a” is a constant). Taking the integral, the first integrand will be an integral in the form $$\frac{u'}{\sqrt{u}}$$ and the second is a standard integral that evaluates to a sine inverse.

### The integral ∫ log x^2/(2log x^2 + log(36 - 12x + x^2)) for (x → 2,4) dx is equal to asked Oct 13, 2018 in Mathematics by Samantha ( 38.8k points) integral calculus

Textbook Authors: Anton, Howard, ISBN-10: 0-47064-772-8, ISBN-13… $$= (2x+5)^{10} \cdot \frac{ 11 \cdot 12 \cdot 2 \cdot 2x }{4 \cdot 11 \cdot 12} = (2x+5)^{10} \cdot x$$ While Stano is formally correct (and some graders might actually penalize you for writing things that way in an exam solution), I frequently see people put the two different variables under the same integral sign in calculation work. Feb 10, 2011 Here, the idea is to make a substitution that will simplify the given integral. For example, the choice u = x2 +1 simpli es the integral: Z 2xdx x2 +1! Z du u Example 10{7: Evaluate the integral Z x4 +1 2 4x3 dx. Solution: u = x4 +1 ) du = 4x3 dx The new integral is: I = Z u2 du = u3 3 +c But we have to express this in terms of the original integral, or just integral of f. Any integral is denoted f x dx We emphasize that any two integrals of a given function differ by a constant.

Then. du = dx, v = ∫ 2xdx = 2x ln2.

He provides courses for Maths and Science at Teachoo. This is only for those who can remember simple Calculus. If not familiar with Calculus, you would describe this in English as the integral of 2x with respect to the change in x evaluated from 10 to 13. The solution is x Squared (i.e. x*x) evaluated from 13*13 - 10*10 or 169-100. Solved: Evaluate the definite integral.
