b.tanA/1+secA=tanA/2

Answers

Answer 1

Answer:

[tex]\frac{tanA}{1+secA} = tan (\frac{A}{2} )[/tex]

Explanation:

Given    

                     =      [tex]\frac{tanA}{1+secA}[/tex]

                        [tex]= \frac{\frac{sinA}{cosA} }{\frac{1+cosA}{cosA} }[/tex]            

                           = [tex]\frac{sinA}{1+cosA} = \frac{2sin\frac{A}{2} cos\frac{A}{2} }{2cos^{2} \frac{A}{2} }[/tex]

                           [tex]= tan\frac{A}{2}[/tex]

Reread the portion of "Through the Tunnel" that describes Jerry’s journey through the tunnel. How does word choice create a sense of danger and suspense? Your response should be at least 150 words.

Answers

Answer:

The diction, or word choice, of Doris Lessing's description of Jerry's swim through the tunnel is suspenseful as it creates anticipation of Jerry's successful passage, and the sense of danger is certainly created through the selective use of certain words.

Explanation:

Idk if this is 150 word, but I hope this helps!! UwU

Answer:

The author created several suspense emotions during Jerry's swim through the tunnel. " There was no strain on his lungs. He felt like an inflated balloon, his lungs were so light and easy, but his head was pulsing," Dorris Lessing quoted in paragraph 36. In paragraph 36 it illustrates how Jerry was going through it, which makes the readers become more curious if the boy would make it out alive. It gives the readers a suspense feeling that makes them wonder if Jerry has enough air and will he survive. The entire paragraph 39 really puts the readers at the edge of their seats, because they are more curious to find out if the poor boy will make it out alive. It gives a full description of the entire experience that Jerry was going through and exactly what he was thinking. The details in paragraph 39 are very descriptive, which helps the reader's imagination, and it boosts the suspense feeling. These are a few reasons for how the author created several suspense moments during Jerry's swim through the tunnel.

Explanation:

I did this whenever I was in High School on common-lit. If you read paragraph 34 - 39 the entire scene is actually filled with suspense. Just use your imagination while you're reading paragraph 34 -39 and I bet you that you'll receive that suspense feeling as well.

metaphor

a figure of speech that is used to make a comparison between two things  that aren't similar, but they have some characteristics in common.

A example would be You are a light of my life (it doesn't mean that something is literary light to someone, no one can provide physical light. This metaphor means that someone brings happiness to another one).

it creates an image of how miserable Negro men and women were, how they endured their hard lives, so that decided to rise in a protest. The mood is tense at first, then it creates an uplifting mood, full of strength to fight the injustice.

use of these metaphors helped a writer to depict creatively and interestingly about the feelings and life of men and women. It helped to create a strong image in the readers

What is suspense?

Suspense is defined as a feeling of unease, uneasiness, doubt, or uncertainty in the mind. Withholding information and posing important questions that stimulate readers' interest are two ways to create tension. Suspense is greatly influenced by character development; for instance, if a character's wish is not granted at the book's conclusion, the novel will not feel satisfying to the reader.

In fiction, foreshadowing creates tension and intrigue to attract readers and pique their curiosity. This literary technique is typically employed to raise readers' expectations for what might occur next and thereby heighten the dramatic tension in a story.

Thus, to analyze an author’s use of suspense, the author’s use of word choice to create tone. Hence option c is correct.

Explanation:

Problems do not enter into the novels of Hamsun in the same manner as they did Into the plays of Ibsen. Hamsun would seem to take life
as it is not with any pretense at its complete acceptability, but without hope or avowed intention of making it over. If his tolerance be never free
from satire, his satire is on the other hand always easily tolerant. One might almost suspect him of viewing life as something static against which all
fight would be futile. Even life's worst brutalities are related with an offhandedness of manner that makes you look for the joke that must be at the
bottom of them. The word reform would seem to be strangely eliminated from his dictionary, or, if present, it might be found defined as a
humorous conception of something intrinsically unachlevable.
(from Edwin Björkman's introduction to Pan, by Knut Hamsun)
Based on the distinction drawn between Hamsun and Ibsen, which inference seems most reasonable?
1. Ibsen's work references an ideal, utopian world.
2. Ibsen is a writer concerned with how problems can be fixed or mitigated.
03. Ibsen's work avolds issues and problems and focuses on eternal themes, like love and herolsm.
4. Ibsen is a writer obsessed with the horror and tragedy of human existence.

Answers

Answer:

Based on the distinction drawn between Hamsun and Ibsen, the inference that seems most reasonable is:

2. Ibsen is a writer concerned with how problems can be fixed or mitigated.

Explanation:

The work of Norwegian writer Henrik Ibsen focused on social issues considered taboo during the 19th century, such as sexually-transmitted diseases and sexism. It is not that Ibsen was fascinated with horror or tragedy. Rather, he was brave and bold enough to approach such themes and even present a controversial way of dealing with them. In the play "A Doll's House", for instance, Nora ends up leaving her abusive husband.

Having that in mind and taking the passage into consideration, we can see that Ibsen is a writer concerned with how problems can be fixed or mitigated. While Hamsun seems to view social problems as tolerable and humorous, as something not worth fighting against, Ibsen sees them as central, important, and changeable.

Were you surprised by the twist at the end of the story? What does it change about your views on Alexander's struggle for liberation? What specific events now appear in a new light?

Answers

Answer and Explanation:

This question is about "A soldier for the crown"

1. The turnaround at the end surprises the reader, since that is what the twists and turns in narrative works are for. This surprise is caused by all the suspense that the author imposes on the work, which besides being dramatic, stimulates the reader's reactions.

2. Alexander's struggle for liberation is more important so that her life is not only full, but that she has the minimum possible quality of life that only liberation can provide.

3. With that, all the actions that Alexandrer (Doroth) become clearer, we were able to analyze the character more deeply and understand all the positions, arguments and opinions that she has.
