prove that
cos^2(pi/2_thita/4)_sin^2(pi/4_thita/4)=sin thita/2
please help me..
Answer:
See below.
Explanation:
Using the identity sin^2x - sin^2x = cos 2x
cos^2( π/4 - Ф/4) - sin^2(π/4 - Ф/4) = cos 2(π/4 - Ф/4)
= cos(π/2 - Ф/2)
Now cos(π/2 - Ф/2) = cosπ/2 cos Ф/2 + sin π/2 sin Ф/2
But cos π/2 = 0 and sin π/2 = 1 so
cos(π/2 - Ф/2) = 0 * cos Ф/2 + 1 * sin Ф/2
= sin Ф/2.

The mason singing his as he makes ready for work, or leaves off work,
The boatman singing what belongs to him in his boat, the deckhand
singing on the steamboat deck,

he stands

ow do the underlined words and phrases in the passage create meaning? They explain the porter's anxiety at meeting a well-known man. They set up a threatening conflict between Sindbad and the porter. They describe the layout of the dining hall and the porter's location in it. They demonstrate Sindbad's respectability and his generosity toward the porter.
This question is incomplete because the passage is missing; here is the complete question:
Read the passage from "The Seven Voyages of Sindbad the Sailor.”
[The porter] followed the servant into a vast room, where a great company was seated round a table covered with all sorts of delicacies. In the place of honor sat a tall, grave man, whose long white beard gave him a venerable air. Behind his chair stood a crowd of attendants eager to minister to his wants. This was the famous Sindbad himself. The porter, more than ever alarmed at the sight of so much magnificence, tremblingly saluted the noble company. Sindbad, making a sign to him to approach, caused him to be seated at his right hand, and himself heaped choice morsels upon his plate, and poured out for him a draught of excellent wine, and presently, when the banquet drew to a close, spoke to him familiarly, asking his name and occupation.
How do the underlined words and phrases in the passage create meaning? A. They explain the porter's anxiety at meeting a well-known man.
B. They set up a threatening conflict between Sindbad and the porter.
C. They describe the layout of the dining hall and the porter's location in it.
D. They demonstrate Sindbad's respectability and his generosity toward the porter.
The answer to this question is D. They demonstrate Sindbad's respectability and his generosity toward the porter.
Explanation:
In the passage, the narrator describes a meeting between the porter and Sindbad who is a respectable man. The idea of respectability is emphasized by the underlined sections such as "a tall, grave man, whose long white beard gave him a venerable air" that shows this man is venerable, and therefore respectable or "This was the famous Sindbad himself" because the word famous emphasizes this quality. Additionally, underlined sections such as "heaped choice morsels upon his plate" or "spoke to him familiarly" show Sindbad is generous with the porter because he does not mind sharing his food and benefits with the porter and is kind when he speaks to him.
