prove the following identities
b.tanA/1+secA=tanA/2

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]

Please help ASAP, I'll also post pic of link to view and edit in goo gle doc because I also have other questions on this assignment or you can answer just this question here I just need help because I'm backed up on a lot of class work, in the names by billy collins what do you notice about the ethnicity and gender of the names? what is the significance of the chosen
poem:

The Names
Yesterday, I lay awake in the palm of the night.
A soft rain stole in, unhelped by any breeze,
And when I saw the silver glaze on the windows,
I started with A, with Ackerman, as it happened,
Then Baxter and Calabro,
Davis and Eberling, names falling into place
As droplets fell through the dark.
Names printed on the ceiling of the night.
Names slipping around a watery bend.
Twenty-six willows on the banks of a stream.
In the morning, I walked out barefoot
Among thousands of flowers
Heavy with dew like the eyes of tears,
And each had a name --
Fiori inscribed on a yellow petal
Then Gonzalez and Han, Ishikawa and Jenkins.
Names written in the air
And stitched into the cloth of the day.
A name under a photograph taped to a mailbox.
Monogram on a torn shirt,
I see you spelled out on storefront windows
And on the bright unfurled awnings of this city.
I say the syllables as I turn a corner --
Kelly and Lee,
Medina, Nardella, and O'Connor.
When I peer into the woods,
I see a thick tangle where letters are hidden
As in a puzzle concocted for children.
Parker and Quigley in the twigs of an ash,
Rizzo, Schubert, Torres, and Upton,
Secrets in the boughs of an ancient maple.
Names written in the pale sky.
Names rising in the updraft amid buildings.
Names silent in stone
Or cried out behind a door.
Names blown over the earth and out to sea.
In the evening -- weakening light, the last swallows.
A boy on a lake lifts his oars.
A woman by a window puts a match to a candle,
And the names are outlined on the rose clouds -
Vanacore and Wallace,
(let X stand, if it can, for the ones unfound)
Then Young and Ziminsky, the final jolt of Z.
Names etched on the head of a pin.
One name spanning a bridge, another undergoing a tunnel.
A blue name needled into the skin.
Names of citizens, workers, mothers and fathers,
The bright-eyed daughter, the quick son.
Alphabet of names in a green field.
Names in the small tracks of birds.
Names lifted from a hat
Or balanced on the tip of the tongue.
Names wheeled into the dim warehouse of memory.
So many names, there is barely room on the walls of the heart.

People have looked at the night sky throughout history. In fact, ancient sailors used the stars as a tool. For example, Polaris, or the North Star, has historically been a useful compass because it is always in the northern sky. At first, people used their eyes to study the stars. Eventually, telescopes were invented. One famous astronomer, Galileo Galilei, made a telescope that was similar to the ones we use today. He used it to prove that Earth revolved around the sun. Astronomers since have made many discoveries with more powerful telescopes. What information can the reader gain from the text feature that is not discussed in the exerpt?

Struggling in quicksand creates a vacuum, which causes a person to sink. But the human body is more buoyant in quicksand than it is in fresh or ocean water, meaning that it is actually easier to float on quicksand than it is in a pool or the ocean. _____ falling into quicksand, a person should slowly spread-eagle and allow the body to gradually come to a back-floating position. By moving cautiously in this position, the quicksand victim can then maneuver back to solid ground and out of danger.

A. after
