What is the first derivative of the function x*sinx+cosx ?

We'll differentiate the function with respect to
x.


We'll note the function as y =
f(x):


dy/dx = d/dx(x)*sinx + x*d/dx(sin x) +
d/dx(cosx)


dy/dx = sin x + x*cosx - sin
x


We'll eliminate like
terms


dy/dx = x*cosx


The first
derivative of the function f(x) is:


f'(x) =
x*cos x 

what kind of system of government is Nigeria operating with, cause the presidential system i think they are operating is not really working.system...

Nigeria operates under a federal republican model, based
on that of the United States, with influences from the British Westminster system. Like
in the USA, the president is both head of state and head of
government.


Nigeria's preidential system does work well,
however within the context of Nigerian politics, this is highly subjective. The Nigerian
President fulfils the requirements of the Constitution, but like so much in Nigerian
politics is conducted against a backdrop of of high levels of corruption and
prebendalism.


Nigeria is still regarded as 'democratic',
though the above problems are persistent. Even so, election irregularities are not seen
to be a major problem and do not compromise the overall presidential
system.


Nigeria certainly hasn't reached the point of
despotism or dictatorship.

In To Kill a Mockingbird, how do the adults deal with the outcome of the trial?

Alexandra has the attitude
that of course this is what would have happened, but she is disappointed for Atticus'
sake. She does deeply care about her brother. She was also upset that he would allow the
children to be exposed to the trial:

“I’m sorry, brother,” she murmured. Having never
heard her call Atticus “brother” before, I stole a glance at Jem, but he was not
listening.


“I didn’t think it wise in the first place to
let them—”


“This is their home, sister,” said Atticus.
“We’ve made it this way for them, they might as well learn to cope with
it.”


“But they don’t have to go to the courthouse and
wallow in
it—”



Atticus
is exhausted emotionally and physically. He also feels the pain of
watching justice denied as evidenced by these words:

“I’m not bitter, just tired. I’m
going to bed.”


“Atticus—” said Jem
bleakly.


He turned in the doorway. “What,
son?”


“How could they do it, how could
they?”


“I don’t know, but they did it. They’ve done it
before and they did it tonight and they’ll do it again and when they do it—seems that
only children weep.
Good night."



Bob
Ewell
spits tobacco in Atticus' face. He obviously is not over the fact
that Atticus smeared his reputation as if there was much of any positive reputation to
begin with.


Maudie Atkinson
honors Atticus with her speech to the children and recognizes his ability to act on
behalf of the entire community in these words:

“I simply want to tell you that there are some
men in this world who were born to do our unpleasant jobs for us. Your father’s one of
them."


“We’re the safest folks in the world,” said Miss
Maudie. “We’re so rarely called on to be Christians, but when we are, we’ve got men like
Atticus to go for
us."



The Negro
community
is appreciative and shows it by flooding Atticus with
food:

Calpurnia said, “This was all ‘round the back
steps when I got here this morning. They—they ’preciate what you did, Mr. Finch.
They—they aren’t oversteppin‘ themselves, are
they?"



The
ladies of Maycomb respond at the Missionary Tea by noting
how dreadful their black servants are. This demonstrates that they still have great
prejudice even though the think they have done the black community a
favor.

In To Kill a Mockingbird, how does Aunt Alexandra help contribute to Scout's development from a tom boy into a lady?

Scout clashes with Aunt Alexandra for most of her early
childhood.  Scout sees her as stuck-up and thinks she does not understand children. 
After Aunt Alexandra comes to live with them, things actually get worse for a while
because Alexandra tries to turn Scout into a lady by making sure she wears dresses,
attends social gatherings of the ladies.  She tries to encourage Scout to appreciate her
heritage, but focuses at first on how the Finch family is better than everyone else. 
This is exactly the opposite of the teachings Atticus has given her.  Atticus has taught
her to respect everyone, no matter how poor or what
race.


Aunt Alexandra does play a pivotal role in Scout’s
coming of age though.  As Scout matures, she comes to understand Alexandra.  She
realizes that Alexandra actually does not approve of some of the bigoted remarks that
the ladies make, and that she does worry about her brother.  Ultimately, it is their
love of Atticus that unites them and allows Scout to see that Alexandra does come from a
place of having Scout’s best interests at heart.  She is trying to teach Scout how to
survive in the world that exists, and Atticus is trying to teach her to change it, or at
least not accept it.  Ultimately, both are lessons she needs to
learn.

What is the overall meaning of the poem "Saint Judas" by James Wright?

"Saint Judas" is a Petrarchan sonnet, with variations to
form, meter and rhythm, that recasts the story of Judas Iscariot, the betrayer for
thirty pieces of silver of Jesus of Nazareth. Written in first person, Judas tells his
inner feelings and thoughts. Critical opinion is that, as is the case with Robert
Browning's "Porphyria's Lover," the character of the poem can only be perceived
sympathetically from within his own perceptions--from his inner
being.


The meaning is that Judas Iscariot regrets his
action of selling out Jesus for silver and of giving him a kiss of betrayal in the
Garden of Gethsemane. He has a rope in hand and is caught in the poem while on his way
to the field in which he intends to hang himself in inconsolable remorse. On the way, he
encounters a man who desperately needs help and Judas unflinchingly, unselfishly rushes
in to his aid. After rescuing the stranger, Judas drops his rope and ignores the
soldiers who are around as he rushes to comfort the beaten
man.


The poem ends with the overall meaning stamped in
images as Judas, who believes he is cast from heaven and has no hope to cling to,
holding the beaten man; he "held the man for nothing" close in his arms. The actions and
images convey the picture of Judas' humanity and selflessness and spiritual
generosity.

What is the form of the poem "Love’s Philosophy" by Percy Bysshe Shelly? For example is it an ode, sonnet, etc.?

It is somewhat difficult to identify the form of Shelley's
"Love's Philosophy."


It certainly is not a sonnet, because
a sonnet has--by definition--14 lines, and Shelley's poem has
16.


Is it an ode?  An ode is a poem that is written in
praise of, or dedicated to someone or something that has inspired the poet.  Does
Shelley's poem fit this definition?  The poem is addressed to someone with whom the poet
would like to "meet and mingle" in romantic fashion.  Yet there is no praise for this
person in the poem.  Rather, the poet repeats, through various examples, that it is "a
law divine" that various beautiful phenomena of nature should meet and mix: "fountains
mingle with the river," "the mountains kiss high Heaven," "the waves clasp one another,"
the "sunlight clasps the earth," etc.


Perhaps it is safest
to say about the form of "Love's Philosophy" is that is a beautiful poem consisting of
two 8-line stanzas.  The rhyme scheme in each stanza is ABABCDCD.  The poet achieves
formal unity by ending each stanza with a question addressed to his
beloved.


It is also interesting to note that subject of
Stanza 1--fountains-- rhymes with the subject of Stanza
2--mountains.

Describe the elements that make Emily mysterious.

Additionally, Emily's description as a "vision of the
past", and her house as a "monument" of the Old South give the reader a sensation of
nostalgia and loss which added up to her persona of mystery. We only get tidbits of
information about her family, such as the fact that her father was authoritarian and
controlled her life, and that her boyfriend, Homer, was disliked. We also wonder about
that. How come she ended up with Homer? What inner fascination did Emily have with a man
of that class? It is what we know that gives her that air of mystery, but what we do not
know is left to a lot of scary thoughts.

Calculate tan(x-y), if sin x=1/2 and sin y=1/3. 0

We'll write the formula of the tangent of difference of 2 angles. tan (x-y) = (tan x - tan y)/(1 + tan x*tan y) ...
