Define surveying. Explain its importance for civil engineers.

I'm just going to say, you know, pretty straightforward that algebra, uh, it's super important. Super important. I would just kind of piggy back of all the facts that we've been doing, um, you know, we're manipulating equations. You know where since by definition, all the reciprocal tangent is equal to sign over cosine. Um, you know, we have all the reciprocal functions. We have to be ableto ad, subtract, multiply, divide fractions. Because they're all of these. These rules, we need to know the trig identities, you know, to be able to simplify science. Worthless coastline squared equals one. We've been using the quadratic formula for another factoring, greatest common factor. Factoring. Try no mules. I can't emphasize enough how important um, algebra is to solving trick equations on kind of a blanket statement would be that you use a lot of algebra, uh, e use, You know, several sections from algebra in this unit. Yeah, I'm just gonna underline that. I think that's good enough for you.

And I will talk about a problem. 10 from chapter one in this problem, um were asked to explain why scientists must study sort of matter and changes in matter on a such a small scale. And nano Scott, big scale. And so changes on this scale, this really small scale, uh, is really concerned with atoms and molecules. So these atoms and molecules are what are on this scale. They're that small. But changes on this scale will cause change to the macro Scott property. So, uh, the things that we see are effective by changes on the Nana Scott Wick scale. And so, since these changes on this small scale effect macroscopic the big scale, we need to study what happens, um, to Adam's molecules on the small scale, to understand what's happening.

Okay, so this question wants you to explain. My graphing can be an important tool for analyzing data so graphing, whether you're talking in terms of a circle grava Bora graph a line graph or essentially any other type of graph is the way that it makes it easier to see patterns and trends in your data. So, for example, if you look at Table 2.4 in the book, it chews you sources of chlorine in the stratosphere, and it lists several sources and their overall percentages. So if you look at this data, you know, you might be able to get some information just by looking at the table. However, if you put it in a circle graph, it makes it a lot easier to visualize because you can actually see directly the percentage that each of these sources of chlorine in the stratosphere make up out of your tool percentage. And further, you can even analyze it. As in this case, buy manufactured compounds and natural sources, and you can definitely see the trend the fact that you have a much higher percentage of manufactured compounds versus national sources as sources of chlorine in the stratosphere So any time you have a graph, it just makes it easier to see patterns and trends and really just understand your data to a better extent.

So this question wants you to explain by standard units of measurement are particularly important to scientists. So without a scientific community, be important to have some type of standard unit of measurement so that you can and you and other scientists can directly compare data. So let's say you were in a lab and you measured the density of substance like Super Loop, and then you have a scientist in Russia also determines the density of superlatives. Having a standard unit of measurement allows you to directly compare your data with the data of another scientist, whether in the same country or in a different country, and compare your data. And so it just makes science better able to be communicated throughout this community.
