We are asked to simplify cos theta - sec theta / sin theta in terms of sine and cosine. sec theta is the inverse function of cos theta. This results to the expression : (cos theta - 1/ cos theta)/sin theta ( cos^2 theta - 1) / sin thetafrom the trigonometric identity which is cos^2 theta + sin^2 theta = 1; 
-sin ^2 theta / sin theta this is equal hence to -sin theta.

What views are being communicated about the Europeans in their role as imperialists?
BaLLatris [955]

 European civilization experienced a period of unprecedented rapid expansion around the globe during the last third of the nineteenth century. European nation-states had become very powerful because of industrialization and because of the organizational efficiency of the nation-state.

European global expansion had actually begun in the fifteenth century, but the process greatly accelerated in the nineteenth century.

Latin America and the seaports of Asia and Africa were the first to be colonized by Europeans. Native Americans were liquidated or thoroughly subjugated to European rule.

 Most Latin American descendents (Latinos) of the Spanish conquerors  gained independence from Spain by the early 19th century, while many indigenous peoples remained subject.

If you choose to write a newspaper article, be sure to include the following in your response: Where is the immigrant group you
Vinil7 [7]

Answer:

The United States is a country that has been populated, built, and transformed by successive waves of migration from almost every part of the world. This reality is widely recognized in the familiar image of the United States as a “nation of immigrants” and by the great majority of Americans, who fondly trace their family histories to Asia, Africa, or Europe or to a mix of origins that often includes an ancestry from one or more of the many indigenous peoples of the Americas. The American national mosaic is one of long standing. In the 18th century, Jean de Crèvecoeur (1981 [1782]) observed that in America, “individuals of all nations are melted into a new race of men.” More than two centuries later, the American experiment of E Pluribus Unum continues with one of the most generous immigration policies in the world, one that includes provisions for diversity, refugees, family reunification, and workers who bring scarce employment skills. The United States is home to almost one-fifth of the world’s international migrants, including 23 million who arrived from 1990 to 2013 (United Nations Population Division, 2013). This figure (23 million net immigrants) is three times larger than the number of immigrants received by any other country during that period.

The successful integration of immigrants and their children contributes to the nation’s economic vitality and its vibrant and ever-changing culture. The United States has offered opportunities to immigrants and their children to better themselves and to be fully incorporated into this society; in exchange “immigrants” have become “Americans”—embracing an American identity and citizenship, protecting the United States through service in

Nation-states are very much like organisms. They are born, they grow, they need nourishment, and they eventually decline and die
emmainna [20.7K]

Answer: B) The Organic Theory

Details:

The Organic Theory of geography -- or maybe more accurately, of geopolitics -- was proposed by German geographer Friedrich Ratzel in 1897.  He suggested that nations function similarly to living organisms.  The controversial part of his theory was that the way a living organism takes in nourishment to grow and thrive, strong nations naturally will nourish and expand themselves, taking in weaker nations or cultures around them.  Ratzel coined the term "Lebensraum" (German for "living space"), which originally, in his view, meant the space for a strong nationalist culture to grow.  His writings came only a few decades after the German Empire had been reborn as the "Second Reich" (second kingdom), a renewal of the older "Holy Roman Empire" of German states as they were linked together in the medieval era.  Ratzel's ideas about "Lebensraum" later were picked up by Hitler and the Nazis as a justification for expanding German territory and taking over neighboring countries.  Germany's expansion under the Nazis as the "Third Reich" led to World War II in Europe.
