For example, a definite integral of a velocity function gives the accumulated distance over the period. You should also be growing more comfortable with how the units work – for example, integrating meters per second with respect to seconds gives meters.Your job is to find an article that refers to a definite integral. It is possible that you will be able to find an explicit mention of a definite integral. Much more likely, though, the definite integral will be implied – the article will actually be about accumulated change. You may look on the Internet, or in any newspaper, magazine, or trade journal. Your example must come from a setting outside of calculus. In particular, you may not use any example from our textbook, any other math textbook, or any other discussion of calculus you find online.

1. A copy of the article with complete source information. Highlight or write the part of the article that mentions the definite integral. 2. Write a few sentences telling what the integrand (the function inside the integral) represents, what the limits of integration are, and what the definite integral represents.3. Assign some letters to the variables here. Using the letters/variables you have chosen, write the definite integral that you have found. Show that the units work properly in your example. (I do not expect you to compute anything here.)

a. Prove that for any vector space, if an inverse exists, then it must be unique.

b. Prove that the additive inverse of the additive inverse will be the original vector.

c. Prove that the only way for the magnitude of a vector to be zero is if in fact the vector is the zero vector.

In each case below either show that the statement is True or give an example showing that it is False.

(V) If {x1, x2, . . . xk, xk+1, . . . xn} is a basis of R n and U = span{x1, . . . xk} and V = span{xk+1 . . . xn}, then U ∩ V = {0}.

1. Solve the following word problem. You should get infinite solutions. So find the pattern for them and give a range of t values that is possible based on the word problem. A trucking company plans on buying 4 kinds of trucks: a pick-up, a small flatbed, a large flatbed, and a dump truck. The pick-up needs one worker to operate, 4 hours of maintenance and 3 hours of cleaning. The small flatbed needs one worker to operate, 1 hour of maintenance and 1 hour of cleaning. The large flatbed needs one worker to operate, 3 hours of maintenance and 2 hours of cleaning. The dump truck needs 2 workers to operate, 3 hours of maintenance and 2 hours of cleaning. If the company has exactly 46 workers, exactly 140 hours for maintenance and exactly 112 hours for cleaning. How many of each kind of truck should they purchase?

[20 points]
defined by
dx =x(2 − 0.4x − 0.3y), x(0) = 4 dt
dy =y(1 − 0.1y − 0.3x), y(0) = 3 dt
where the populations x(t) and y(t) are measured in thousands and t in years. Use a step size of 0.2 for 0 ≤ t ≤ 2 and plot the trajectories of the populations with Matlab or GNU Octave.

Question H:

Let’s keep using the AM-radio style signal from Question G: f(x) = sin(12x) * sin(x) on [0,2*pi].

It’s okay to use Wolfram Alpha or Desmos to do the following integrals.

i)

 Integral Numeric result (1/pi)*integral of f(x)*cos(1x) dx from 0 to 2pi (1/pi)*integral of f(x)*cos(2x) dx from 0 to 2pi Etc., with cos(3x) ...cos(4x)... ...cos(5x)... ...cos(6x)... ...cos(7x)... ...cos(8x)... ...cos(9x)... ...cos(10x)... ...cos(11x)... ...cos(12x)... ...cos(13x)... ...cos(14x)...

ii) What do you get if you graph 0.5*cos(11x)+-0.5*cos(13x) ?
