R x2 cos(x)dx Answer: Z The second integral can be rewritten as the di erence of the areas of two triangles. Z 1 3 2xdx= Z 0 1 2xdx Z 3 0 dx= 1 9 = 8: The third integral can be viewed as the area of a sector of radius ˇwith a triangle removed. The value is ˇ=8 1=4. Remark. A careful student might complain that this exercise requires circular rea-soning.

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 . 8 − + · Thomas’ Calculus 13th Edition answers to Chapter 5: Integrals - Section 5.6 - Definite Integral Substitutions and the Area Between Curves - Exercises 5.6 - Page 303 9 including work step by step written by community members like you. 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 [math](2xy+y)dx+(x^2-x)dy[/math], you mean [math]\int (2xy+y)dx+\int (x^2-x)dy[/math]. To solve this equation, it should be considered a single variable integral: [math]\int (ax)dx[/math], 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 definite integral of from to , denoted , is defined to be the signed area between and the axis, from to . Both types of integrals are tied together by the fundamental theorem of calculus. This states that if is continuous on and is its continuous indefinite integral, then . This means . Sometimes an approximation to a definite integral is

Since we have exactly 2xdx in the original integral, we can replace it by du: Z 2xcos(x2)dx = Z cosudu = sinu+C = sin(x2)+ C. This is not the only way to do the algebra, and typically there are many paths to the correct answer.

To solve this equation, it should be considered a single 1−3cos2x+3cos2 2x− cos3 2xdx.
